A remote delivery offering that emphasizes the correlation of structure and chemical bonding in carbon compounds with the physical properties and chemical reactivity of organic molecules. Discussion will be based on functional groups with emphasis on hydrocarbons and derivatives that contain halogens, oxygen, sulfur, and the hydroxy group. Introduction to stereochemistry, three-dimensional structure, reaction mechanisms, especially addition to double bonds, nucleophilic substitution and elimination reactions. Seminars will emphasize virtual laboratory techniques and online workshops for IR spectroscopy and stereochemistry. Prerequisite CHEM 101 or 103. Note: Students who have obtained credit for CHEM 261 cannot take CHEM 264 for credit.
