    Learning Objectives

    After you have completed Chapter 8, you should be able to

    1. full fill all of the detailed objectives listed under each individual section.
    2. use the reactions discussed, along with those from previous chapters, when designing multi-step syntheses.
    3. use the reactions and concepts discussed to solve road-map problems.
    4. define, and use in context, the key terms introduced.

    You have already studied the chemistry of compounds that contain one carbon-carbon double bond. In this chapter, you will focus your attention on compounds that contain two or more such bonds. In particular you will study the properties of those compounds that contain two carbon-carbon double bonds which are separated by one carbon-carbon single bond. These compounds are called “conjugated dienes.”

    To understand the properties exhibited by conjugated dienes, you must first examine their bonding in terms of the molecular orbital theory introduced in CHM 222. Then, you must learn how the products of a reaction are dependent on both thermodynamic and kinetic considerations. Which of these two factors is the most important can sometimes determine which of two possible products will predominate when a reaction is carried out under specific conditions.
