Course Description:  This lab has been designed to complement the Organic Chemistry I course.  It will enable you to apply concepts introduced in Organic Chemistry I, which introduces fundamental concepts including structure, melting point, distillation, extraction, chromatography, stereochemistry, synthesis of organic compounds, and reaction mechanisms of the major classes of organic compounds.

Course Themes: Organic Chemistry Lab Techniques

Upon completion of the course, students should be able to:

• Demonstrate the theory and principles of fundamental laboratory experiments which reinforce the concepts covered in the lecture course
• Follow experimental procedures carefully
• Use good laboratory techniques rigorously, adhering to the rules regarding lab safety 
• Relate the application of organic chemical reactions to everyday life and other fields of science
• Keep a neat and up-to-date notebook, written using correct grammar, that represents an accurate accounting of the work done

Required Text:  Organic Chemistry Laboratory Experiments, Professors Madhu Pandey and Henry Alegria, University of South Florida St. Petersburg: McGrawHill

 

Additional Requirements:

1. Active e-mail account (Essential for communication regarding labs and consultation appointments)
2. A laboratory notebook with copy pages (available at the bookstore)
3. Safety goggles (we will have some available for your use but I advise you to purchase your own)
4. Writing implements, rulers and scientific calculators (do not assume these will be provided)

 

Course Design and Assessment: This laboratory course typically requires all 4 hours allotted to it.  Only on rare occasions can you expect the lab to be finished in advance of the allotted time.  Lab begins promptly at the respective start time (e.g., 8:00 AM means 8:00 AM).   Each lab consists of a pre-lab and a post-lab component.  A pre-lab is a document you submit to show that you are prepared for the experiment you will carry out.  A post-lab is your lab report once you have completed the experiment.

You must turn in a pre-lab at the beginning of the class for check/sign.  If you do not turn in a pre-lab you will not be allowed to do the experiment and you will earn a zero (0) for that lab.  This rule will be rigorously enforced.

A pre-lab must contain the following sections:

1. Name
2. Title of Lab
3. Purpose / goal(s) of the lab / theory / background (i.e. an introduction) - a brief section that discusses what you will be doing, how you will be doing it, the theory behind the experiment, relevant graphs and/or equations, and a science-based hypothesis about what you expect for the outcome of the experiment.
4. Materials – a list of the materials that will be required to complete the lab.
5. Procedure – a list of the steps you will take in the experiment (flowchart if appropriate). 
6. Pre-lab Questions – you must answer the pre-lab questions, if any are assigned. 

Your post-lab report will contain:

1. Name
2. Title of lab
3. Data- your notes as you wrote them while you were doing the experiment
4. Results & Calculations - additional calculations, chemical equations, etc., that you carry out with your results once you have completed the experiment
5. Discussion/Conclusion – a section that ties everything together
6. Post-lab Questions – you will answer a series of questions related to the experiment you completed

(See section below for the detailed Lab Report Template and Rubric)

 

It is imperative that you prepare for each lab. Your level of preparedness is immediately noticed and should I deem that you have not adequately prepared, you will lose points.  Continually being unprepared can result in being asked to leave and earning a zero (0) for that experiment; if this situation is deemed particularly egregious you may be asked to drop the course.  Failure to prepare increases the incidence of sloppy work, and more importantly, accidents.  I will not allow one student’s failure to prepare endanger the safety of the others.

You will be required to keep a laboratory notebook.  The appropriate type of notebook is available in the bookstore.  It is specifically made so that there will be a carbon copy when you write your labs.  You may use either a black or a blue pen.  Pencil or markers are unacceptable. Your experiment begins before you enter the lab.  You will have already read the entire procedure and made note of any questions you may have regarding the lab. 

After you have completed your experiment, you will have to do a post lab analysis at home; this will involve providing your data, writing any results and calculations used, discussing the results of your lab, discussing your hypothesis, and answering any post-lab questions assigned.

At the beginning of the first experiment you will turn in your first pre-lab report.  Thereafter, at the beginning of every lab you will be required to submit a pre-lab for that week’s lab and a report for the previous week’s experiment.  As stated earlier, if you do not have a pre-lab you will not be allowed to do that week’s experiment and you will earn a zero (0) for that lab.  If you do not submit your lab report for the previous week’s lab by the class start time you will lose 20 points. If you do not submit the report the week after that you will lose another 20 points (see Laboratory Report Grade Deductions below). Your graded reports will be returned to you the week after you turn in the report.  You are not permitted to submit your labs to anyone else but me.  If for some reason you need to turn in your lab late, you must come to my office and drop it off.  If I am not in my office, please mark the time of submission on the lab and slip it under the door.

Attendance Policy: Every student is expected to attend every lab session.  You cannot expect to do well in this course if you don't attend class.  Before leaving class you must have your work collected and signed by your instructor in order to receive credit for that day's lab. Leaving lab before you complete your assignment (or without the instructor's approval) will result in no credit for that day's lab. If you miss a lab session, the work cannot be made up the following week! There are no makeup labs. If you miss a lab you earn a zero (0) for that lab, no negotiations.  You have a 2 minute grace period after lab begins to be in class.  At the beginning of each lab I do a brief synopsis of the day’s experiment and give a quiz.  If you arrive late you do not get the benefit of this synopsis.  After 2 minutes, the doors to the lab will be shut, which means you will be interrupting lab in session. If you are more than 2 minutes late, you will not be allowed to perform the lab and you will earn a zero (0).  The lowest lab grade will be dropped, so if you fail to complete one of the labs, the score from that lab will not count against your final lab grade. If you miss a lab, you must submit the pre-lab and post-lab report using the “Inbox” functionality on Canvas. The same point deductions apply as for labs that you attended.

 

Grading Policy: By the end of this course you will have performed eleven labs and the final evaluation, which includes the identification of an unknown.  Each “regular” lab is worth 100 points: 10 for the quiz, 10 points for participation, 30 for the pre-lab and 50 for the post-lab reports. Three of the labs will be from worksheets available on Canvas, and do not have a pre-lab or quiz. Of the eight “regular” labs having a pre-lab, post-lab, and quiz, the lowest grade will be dropped for each of the components (pre-lab, post-lab, participation, and quiz). The first lab, which is Exploring the Organic Laboratory, cannot be dropped. The final lab, which is the Identification of the Unknown, cannot be dropped.  There will also be a cumulative final that will be part practical and part written that is worth an additional 200 points.                 

Assignment of final letter grades is based on the number of points you have accumulated by the end of the semester, out of total points possible:

Grading Scale:

A+ ≥ 97%		B+ ≥ 87%		C+ ≥ 75%		D ≥ 60%
A   ≥ 93%		B  ≥ 83%		C  ≥ 70%		F < 60%
A- ≥ 90%		B- ≥ 80%

 

Late Assignments: See above.

Cellphones:  You are prohibited from using your cellphone during labs.  If it is an absolute emergency you may leave the lab to use the cellphone only after seeking my permission.

Academic Honesty (Excerpt from USF St. Petersburg Student Handbook):

            I do not tolerate academic dishonesty of any kind; this includes cheating as well as plagiarism and its many manifestations.  I will enforce the school policy so please familiarize yourself with the USF St. Petersburg Student Handbook as it holds all regulations for students. 

Disabilities: If you have a disability, which might affect your performance in this class, please contact the Office of Student Disability Services (OSDS) [http://www1.usfsp.edu/disability/index.htm (Links to an external site.)].  Register with OSDS at the beginning of the semester and notify your instructor of your need for accommodations as soon as possible, preferably during the first two weeks of classes.  In accordance to your right to privacy, you may seek an appointment with me outside of class time in which we can discuss your individual situation.

Kimberly Clark Gloves Disposal:  

Currently over 30,000 latex gloves are used per semester in the USFSP Chemistry Labs. In order to reduce our carbon footprint and the amount of gloves in the Pinellas County solid waste landfill USFSP labs have started the Kimberly Clark RightCycle program. This program allows for the labs to return the gloves to a recycling center where they are then transformed into lawn furniture!

Since we have chosen to partake in this program we STRONGLY suggest you think before you toss your dirty gloves! All Kimberly Clark RightCycle gloves (green) should be disposed of in the proper, labeled recycled gloves bin, which can be found in the back of the lab classroom. DO NOT DISPOSE OF NORMAL LATEX GLOVES HERE! We appreciate your efforts!

Lab Report Template and Rubric

Lab reports are an essential part of all laboratory courses and a significant part of your grade. Here is the format for your pre-lab and post-lab report. A lab report is how you explain what you did in the experiment, what you learned, and what the results meant.

 

In Class Quiz: 10 points 

Participation: 10 points

Pre-Lab (30 points):

1. Title Page (if this is in your lab notebook, it can be part of the first page)

• The title of the experiment.
• Your name and the names of any lab partners
• Section number
• Your instructor's name
• The date the lab was performed

Title: The title says what you did. It should be brief (aim for ten words or less) and describe the main point of the experiment or investigation. An example of a title would be: "Measurements of mass, Volume, Length and the Density of Solid and Liquid”. If you can, begin your title using a keyword rather than an article like 'The' or 'A'.

Date:

Lab Partners:

TA and section:  

2. Introduction (5 points) The Introduction is one paragraph that clearly explains the objectives or purpose of the lab (e.g., “The purpose of this lab is to use mass spectrometry to identify an unknown compound.”), and provides some relevant scientific background information. In one sentence, also state a hypothesis.
3. Materials (5 points) List everything needed to complete your experiment. Typically a minimum of 10 items are involved in each experiment (this includes things like lab equipment, safety equipment, chemicals, etc.).

 

4. Procedure (10 points) Describe the steps you completed during your investigation. This is your procedure. Be sufficiently detailed that anyone could read this section and duplicate your experiment. Write it as if you were giving directions for someone else to do the lab. It may be helpful to provide a figure to diagram your experimental setup. This needs to be in your own words – copying from your laboratory notebook or worksheets at any point is plagiarism and will result in actions as described in the syllabus. Furthermore, if you use an image from your notebook, a worksheet, or online, you must cite the source of the image or points will be deducted.
5. Prelab Questions, if any are assigned (10 points) See your course Schedule (available on Canvas as a link towards the top of the Course Syllabus page) for the prelab questions that you are responsible for answering in each lab.

________________________________________________________________________

All of the above are due before you start the experiment!

________________________________________________________________________

Post-lab (50 points):

1. Data (5 points) Numerical data obtained from your procedure usually is presented as a table. Data encompasses what you recorded when you conducted the experiment. It's just the facts, not any interpretation of what they mean. These raw data are collected during the experiment and recorded in your carbon copy workbook. You should make every effort to record it as neatly and coherently as possible. If your hand recorded data section is neatly compiled, there is no need to present it in a typed, tabular format – the page from your workbook may simply be stapled to your typed post-lab. This section will also contain any observations you made during the experiment.
2. Results & Calculations (10 points) The Data section mostly contains numbers. This section contains any calculations you made based on those numbers. In addition, present any mathematical or chemical equations needed.
3. Figures & Graphs if any (5 points) Graphs and figures must both be labeled with a descriptive title. Label the axes on a graph, being sure to include units of measurement. The independent variable is on the x-axis. The dependent variable (the one you are measuring) is on the y-axis. Be sure to refer to figures and graphs in the text of your report. The first figure is Figure 1, the second figure is Figure 2, etc. This will not be necessary for all experiments.
4. Analysis (Discussion / Conclusions) (20 points)Description of why you did the calculations. This is where you interpret the data (and Results), and also where you would discuss any mistakes you might have made while conducting the investigation. You may wish to describe ways the study might have been improved. Identify at least one possible human error and one possible environmental condition that may have caused your results to vary from those expected, and explain how those factors would have caused the variance.Discuss your results and whether you could potentially accept or reject your hypothesis stated in the pre-lab introduction. Be sure to cite specific data, results, and calculations in this section, and state why the data you collected and the results you derived from them support your conclusions. Do not only say something like, “The data indicated that temperature increased as volume increased,” or something else that could have been written before you even did the lab! This statement is fine, but you also need to give specific numbers or other observations that support this conclusion.
5. Post Lab Questions (10 points) See your course Schedule (available on Canvas as a link towards the top of the Course Syllabus page) for the post lab questions that you are responsible for answering in each lab.

References: If your research was based on someone else's work or if you cited facts that require documentation, then you should list these references. Failure to do so will result in plagiarism proceedings.

Student Safety Contract

 

Purpose

          This is a hands-on laboratory class. You will be doing many laboratory activities that require the use of hazardous chemicals. Safety in the science classroom is the #1 priority for students, and instructors. To ensure a safe science classroom, a list of rules has been developed and provided to you in this student safety contract. These rules must be followed at all times.

          Upon completion of the first lab and after reading the information below you must sign the last page and return it to your instructor before leaving. This form must be returned to the instructor before you can participate in future labs. Bring the handouts for this lab to use as a reference and as a constant reminder of the safety rules and equipment.

          Proper laboratory technique is essential to the education of successful students and future scientists. Your success will depend on your attitude and conduct. If you work with an attitude of rushing through, you will profit very little from a poor attitude. An interest in your work, an understanding of its purpose and a clear interpretation of your results are necessary factors for a good laboratory course. The chemistry laboratory is a safe place to experiment if you are careful. You must assume responsibility for the safety of yourself and your neighbors. Following are some safety and procedural rules to help guide you in protecting yourself and others from injury in the laboratory.

 

General Guidelines

1. Conduct yourself in a responsible manner at all times in the laboratory.
2. Take your lab work seriously. Never fool around in the laboratory. Horseplay, pranks, and practical jokes are dangerous and prohibited.
3. Be familiar with your lab assignment before you come to lab. Follow all written and verbal instructions carefully. If you do not understand a direction or part of a procedure, ask the instructor before proceeding.
4. Never work alone. No student may work in the laboratory without an instructor present.
5. When first entering a science room, do not touch any equipment, chemicals, or other materials in the laboratory area until instructed to do so.
6. Do not eat food, drink beverages, or chew gum in the laboratory. Do not use laboratory glassware as containers for food or beverages.
7. Perform only those experiments authorized by the instructor. Never do anything in the laboratory that is not called for in the laboratory procedures or by your instructor. Carefully follow all instructions, both written and oral. Unauthorized experiments are prohibited.
8. Safety goggles and aprons must be worn whenever you work in the lab. Gloves should be worn whenever you use chemicals that cause skin irritations or need to handle hot equipment. Wear older clothes that cover the maximum amount of skin.
9. Observe good housekeeping practices. Work areas should be kept clean and tidy at all times. Bring only your laboratory instructions, worksheets, and/or reports to the work area. Other materials (books, purses, backpacks, etc.) should be stored on the front tables.
10. Know the locations and operating procedures of all safety equipment including the first aid kit, eyewash station, safety shower, spill kit, fire extinguisher, and fire blanket. Know where the fire alarm and the exits are located.
11. Be alert and proceed with caution at all times in the laboratory. Notify the instructor immediately of any unsafe conditions you observe.
12. Dispose of all chemical waste properly. Never mix chemicals in sink drains. Sinks are to be used only for water and those solutions designated by the instructor. Solid chemicals, metals, matches, filter paper, and all other insoluble materials are to be disposed of in the proper waste containers, not in the sink. Check the label of all waste containers twice before adding your chemical waste to the container. The solid waste container is only for chemicals in the solid state, for instance, powder or crystalline reagents and products. Do not throw away paper towels, gloves, or weighboats in the solid waste bucket!
13. Cracked or broken glass should be placed in the special container for “Broken Glass.” This includes used disposable test tubes and capillary tubes. If you drop a piece of glassware and it cracks or breaks, notify your instructor, who will clean it up. Do not attempt to clean up cracked or broken glassware yourself.
14. Labels and equipment instructions must be read carefully before use. Set up and use the prescribed apparatus as directed in the laboratory instructions provided by your instructor.
15. Keep hands away from your face, eyes, mouth, and body while using chemicals. Wash your hands with soap and water after performing all experiments. Clean (with detergent powder), rinse, and dry all work surfaces and equipment at the end of the experiment.
16. Experiments must be personally monitored at all times. You will be assigned a laboratory station at which to work. Do not wander around the room, distract other students, or interfere with the laboratory experiments of others.
17. Students are never permitted in the science storage rooms or preparation areas unless given specific permission by their instructor.
18. Know what to do if there is a fire drill during a laboratory period; containers must be closed, gas valves turned off, fume hoods turned off, and any electrical equipment turned off.
19. If you spill acid or any other corrosive chemical on your skin or clothes, immediately wash the area with large amounts of water (remember that small amounts of water may be worse than no water at all). After this, get the instructor’s attention. The spill kit will be used for spills on floor or counter-top.
20. At the end of the laboratory session see that: a) the main gas outlet valve is shut off, b) the water is turned off, c) desktop, floor area, and sink are clean, d) all electrical equipment is turned off and unplugged, e) all other equipment is cool, clean, and arranged in the correct drawer (see the printout taped to the front of each fume hood for where the equipment goes!).

 Clothing

21. Any time chemicals, heat, or glassware are used, students will wear laboratory goggles. There will be no exceptions to this rule! Contact lenses should not be worn in the laboratory unless you have permission from your instructor.
22. Dress properly during a laboratory activity. Long hair, dangling jewelry, and loose or baggy clothing can be hazards in the laboratory. Long hair must be tied back and dangling jewelry and loose or baggy clothing must be secured. No short skirts, shorts, or sleeveless tops, Shoes must completely cover the foot. No sandals, flip-flops or open-toed, or heeled shoes are allowed. Students will not be allowed to perform lab if they are not properly dressed (penalties apply).

 Accidents and Injuries

23. Report any accident (spill, breakage, etc.) or injury (cut, burn, etc.) to the instructor immediately, no matter how trivial it may appear.
24. If you or your lab partner is hurt, immediately yell out "Code one, Code one" to get the instructor's attention. Everyone should turn off hot plates, burners, and other potentially dangerous equipment and prepare to help if needed.
25. If a chemical should splash in your eye(s), immediately flush with running water from the eyewash station for at least 20 minutes. Notify the instructor immediately.

 Handling Chemicals

26. All chemicals in the laboratory are to be considered dangerous. Do not touch, taste, or smell any chemical unless specifically instructed to do so. The proper technique for smelling chemical fumes is to gently fan the air above the chemical toward your face. Breathe normally.
27. Check the label on chemical bottles twice before removing any of the contents. Take only as much chemical as you need. Smaller amounts often work better than larger amounts. Label all containers and massing papers (boats) holding dry chemicals.
28. Never return unused chemicals to their original containers.
29. Never use mouth suction to fill a pipette. Use a pipette bulb or pipette filler.
30. Acids must be handled with extreme care. ALWAYS ADD ACID SLOWLY TO WATER, with slow stirring and swirling, being careful of the heat produced, particularly with sulfuric acid. Allow to cool.
31. Handle flammable hazardous liquids over a pan to contain spills. Never dispense flammable liquids anywhere near an open flame or source of heat.
32. Never take chemicals or other materials from the laboratory area.
33. Take great care when transferring acids and other chemicals from one part of the laboratory to another. Hold them securely.

 Handling Glassware and Equipment

35. Inserting and removing glass tubing from rubber stoppers can be dangerous. Always lubricate glassware (tubing, thistle tubes, thermometers, etc.) before attempting to insert it in a stopper. Always protect your hands with towels or cotton gloves when inserting glass tubing into, or removing it from, a rubber stopper. If a piece of glassware becomes "frozen" in a stopper, take it to your instructor for removal.
36. When removing an electrical plug from its socket, grasp the plug, not the electrical cord. Hands must be completely dry before touching an electrical switch, plug, or outlet.
37. Examine glassware before each use. Never use chipped or cracked glassware. Never use dirty glassware. Do not immerse hot glassware in cold water; it may shatter.
38. Report damaged electrical equipment immediately. Look for things such as frayed cords, exposed wires, and loose connections. Do not use damaged electrical equipment.
39. If you do not understand how to use a piece of equipment, ask the instructor for help.

 Heating Substances

40. SHOULD THE BUNSEN BURNER GO OUT, IMMEDIATELY TURN OFF THE GAS AT THE GAS OUTLET VALVE. If you wish to turn off the burner, do so by turning off the gas at the gas outlet valve first, then close the needle valve and barrel. Never reach over an exposed flame. Light gas burners only as instructed by the video or instructor.
41. Never leave a lit burner or hot plate unattended. Never leave anything that is being heated or is visibly reacting unattended. Always turn the burner or hot plate off when not in use.
42. You will be instructed in the proper method of heating and boiling liquids in test tubes. Do not point the open end of a test tube being heated at yourself or anyone else.
43. Heated metals, glass, and ceramics remain very hot for a long time. They should be set aside to cool and then picked up with caution. Use tongs or heat-protective gloves if necessary. Determine if an object is hot by bringing the back of your hand close to it prior to grasping it.

 

Campus Safety

USFSP’s Student Sexual Harassment and Violence policy, following national guidance from the Office of Civil Rights, requires that faculty follow USF policy as a “mandatory reporter” of any personal disclosure of sexual harassment, abuse, and/or violence related experiences or incidents shared with the faculty member in person, via email, and/or in classroom papers or homework exercises. These disclosures include but are not limited to reports of personal relational abuse, relational/domestic violence, and stalking. While faculty are often able to help students locate appropriate channels of assistance on campus (e.g., see the USFSP Health and Wellness link below), disclosure by the student to the faculty member requires that the faculty member inform appropriate USF channels to help ensure that the student’s safety and welfare is being addressed, even if the student requests that the disclosure not be shared.

 

For counseling support and assistance, please see the USFSP Wellness Center, which includes a variety of counseling services that can be accessed at: http://www.usfsp.edu/wellness/ And, the Sexual Assault Victim Assistance Team is a confidential resource for students that does not have a reporting requirement and that can be of great help to students who have experienced sexual assault.
