This course introduces students to the fundamental concepts necessary for understanding organic molecules. Include nomenclature, conformational analysis, stereochemistry, functional groups, isomerism, spectroscopy, reactions of alkanes, cycloalkanes, alkenes, alkynes, alcohols, and alkyl halides. Mechanistic theory of organic chemical reactions in the context of acid-base, free radical reactions, nucleophilic substitution, elimination, and electrophilic addition reactions are studied. Three lectures per week. Prerequisite: CHEM 232. Credit, 3 hours. Offered fall semesters.
