Addition reactions not only dominate the chemistry of alkenes, they are also the major class of reaction encountered in the chemistry of alkynes. This unit will discuss an important difference between (terminal) alkynes and alkenes, that is, the acidity of the former; it also addresses the problem of devising organic syntheses. Once you have completed this unit you will have increased the number of organic reactions in your repertoire, and should be able to design much more elaborate multistep syntheses. As you work through this unit, you should notice the many similarities among the reactions described here and those discussed in Units 7 and 8.

Unit Objectives

After you have completed Unit 9, you should be able to

fulfill all of the detailed objectives listed under each individual section.
solve road-map problems involving any of the reactions introduced to this point.
design multistep syntheses using any of the reactions introduced to this point, and determine the viability of a given synthesis.
define, and use in context, the key terms introduced in this unit.
