Chapter 5. Structure and Preparation of Alkenes: Elimination Reatcions.

This Chapter deals with the carbon-carbon (C=C) double bonds as a functional group. We'll discuss the structure of the C=C bond, a stereochemical isomerization resulting from its structure, and how to synthesize C=C bonds through elimination reactions.

Problems: 5.8, 5.9, 5.10, 5.12, 5.13, 5.14, 5.15, 5.16, 5.17, 5.18, 5.19, 5.20, 5.26, 5.28, 5.34, 5.35, 5.36, 5.39, 5.42, 5.44, 5.46
