An introduction to the chemistry of monofunctional aliphatic compounds with emphasis on reactions and their mechanisms. Special topics will include synthetic and natural polymers. Three lectures, one tutorial; one term Prerequisite(s):CHEM 1AA3 or ISCI 1A24 Antirequisite(s): CHEM 2BA3, CHEM 2OA3, CHEM 2OC3, CHEM BIO 2OA3 Students will forfeit credit in CHEM 2E03 if any of CHEM 2BA3, CHEM 2OA3, CHEM 2OC3 or CHEM BIO 2OA3 are subsequently completed. Similarly, students with a program that requires CHEM 2E03 or CHEM 2OA3 and CHEM 2OB3 will forfeit credit in CHEM 2OA3 if they subsequently complete CHEM 2E03. CHEM 2E03 is not a prerequisite for further courses in Organic Chemistry.
