An introduction to bonding and functionality in organic compounds. Qualitative factors affecting acidity and basicity will be introduced, as well as the concept of aromaticity. A mechanistic approach to learning reactions will be emphasized, with discussion of the nucleophilic acyl additions and substitutions, nucleophilic reactions adjacent to carbonyls, simple substitutions, and electrophilic aromatic substitutions. The three-dimensional structure of molecules and the concept of stereochemistry will also be examined. Prerequisite: AUCHE 212; AUCHE 230 is recommended.
