Chapter 6, Problem 20P

Interpretation Introduction

Interpretation:

The alkyl halide, which reacts more rapidly by ${\text{S}}_{\text{N}}2$ mechanism, is to be classified.

Concept introduction:

In organic chemistry, nucleophilic substitution consists of bimolecular reactions, one-step mechanisms, and the carbocation will not form. Thus, this type of reaction is known as ${\text{S}}_{\text{N}}2$ reaction.

In an alkyl halide, the reaction takes place between halogen atoms and alkanes in order to form halogenated hydrocarbons.
