Unit Preview

In this course, you have already seen several examples of nucleophilic substitution reactions; now you will see that these reactions can occur by two different mechanisms. You will study the factors that determine which of these two mechanisms will be in operation in a given situation, and examine possible ways for increasing or decreasing the rates at which such reactions occur. The stereochemical consequences of the two mechanisms will also be discussed. Elimination reactions often accompany nucleophilic substitution; so these reactions are also examined in this unit. Again you will see that two different mechanisms are possible, and, as in the case of nucleophilic substitution reactions, chemists have learned a great deal about the factors that determine which mechanism will be observed when a give alkyl halide undergoes such a reaction.

Unit Objectives

After you have completed Unit 11, you should be able to

fulfill all of the detailed objectives listed under each individual section.
use the reactions studied in this unit with those from previous units when designing multistep syntheses.
use the reactions and concepts discussed in this unit in solving road map problems.
define, and use in context, the key terms introduced in this unit.
