The first term of a two-term introduction to the chemistry of carbon compounds intended for students planning a chemistry major or career of research in a chemically-related science, including medical science. The lectures deal with the preparation, properties, and reactions of most of the important classes of organic compounds. There is considerable emphasis on reaction mechanisms and some attention is given to naturally occurring substances of biological importance. Topics are covered in greater depth, both in lecture and in the textbook, than in the CHEM 51-52 sequence. The laboratory work introduces the student to experimental techniques and instrumental methods including several types of chromatographic and spectroscopy techniques, organic synthesis, and identification of organic compounds. Enrollment in CHEM 57-58 is limited.
