An examination of the structure and reactivity of small organic molecules. Discussion of molecular architecture includes bonding, geometry and conformation. These considerations are applied to a survey of organic reactions, mechanisms and energetic. Emphasis is placed on the development of problem-solving skills and the concise communication of chemical ideas. One laboratory per week. Prerequisite: Completion of CHEM*122 with a grade of "C" or better. Distribution Requirements: QR, SP. CHEM*112 may be used in place of CHEM*122 in satisfying the prerequisite for the above course.
