Chapter 9, Problem 130P

Interpretation Introduction

Interpretation:

The reason for given alkyl halide do not undergo a substitution reaction, regardless of the base use, was to be explained

Concept Introduction:

A good nucleophile/strong base favors ${\text{S}}_{\text{N}}\text{2}$ .

A poor nucleophile/weak base favors ${\text{S}}_{\text{N}}\text{2}$.

In primary alkyl halides and secondary alkyl halide ${\text{S}}_{\text{N}}\text{2}$ take place.

Tertiary alkyl halides undergo ${\text{S}}_{\text{N}}1$ reaction.
