CHEM 261 - Organic Chemistry I

3 units (fi 6)(EITHER, 3-0-3)

Open Study: Spring / Summer

Faculty of Science

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, nitrogen, and the hydroxy group. Introduction to stereochemistry, three dimensional structure, reaction mechanisms, especially addition to double bonds, nucleophilic substitution and elimination reactions. Prerequisite CHEM 101 or 103. Note: Students who have obtained credit for CHEM 264 cannot take CHEM 261 for credit. Engineering students who take this course will receive 4.5 units.
