Chemistry 241 Laboratory – Fall 2010 Place: Keyes 305 Instructors: Prof. Jeffrey Katz, Dr. Edmund Klinkerch Contact Info: Jeff Katz, Keyes 216/210, x5754, jlkatz@colby.edu Edmund Klinkerch, Keyes 308, x5762, ejklinke@colby.edu Office Hours: By appointment or anytime our doors are open! 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. Note: Laboratory material will be incorporated into class exams! This semester you will work with a partner when carrying out experiments in lab, and each 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 before 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.
