GENERAL COMMENTS ABOUT THE LAB
This semester you will be spending four hours a week of your valuable time in the organic
chemistry lab. It is our hope that these hours will be educational, productive, and fun. We are
committed to providing you with a safe lab experience and ensuring that environmentally sound
practices are always followed. Much of this semester is concerned with learning several
fundamental techniques in experimental organic chemistry. These include crystallizations,
melting point determinations, extractions and separations, distillation, and chromatography. You
will be also introduced to molecular modeling using the facilities at the Paul J. Schupf Scientific
Computing Center in Keyes 404. Furthermore, you will be trained in instrumental methods such
as gas chromatography, polarimetry, and IR spectroscopy.
The philosophy of the lab is pretty simple. You are here to learn not only how to do things, but
the underlying concepts as well. We want you to know both what you are doing and why you are
doing it. You will miss a great deal if your goal is to only follow the procedure without thinking,
observing, and questioning.
Laboratory material will be incorporated into class exams!
This semester you will work with a partner when carrying out experiments in lab, and
student team will turn in a single lab report
The success of such a partnership will depend
very much on both of you pulling your weight and working well together.
Both members of the
group will contribute to the writing of reports, and both will receive the same grade.
We are most concerned with your understanding
of the experiments and your level of preparation
for each experiment
you set foot in the lab.
So, while getting a bumper yield of your
intended product is certainly a good thing, you must also be able to recognize when an
experiment has not progressed “perfectly” and be able to explain your actual results. In keeping
