Chapter 9, Problem 9.63P

Interpretation Introduction

Interpretation:

The structures of the synthetic intermediates A and B has to be drawn.

Concept Introduction:

${\text{S}}_{\text{N}}\text{2}$ reaction:

The rate of the reaction is depends on both substrate and nucleophile in a reaction is known as ${\text{S}}_{\text{N}}2$ bimolecular nucleophilic substitution. In ${\text{S}}_{\text{N}}2$, addition of nucleophile and removal of leaving group takes place simultaneously. Hence, the rate of ${\text{S}}_{\text{N}}2$ reaction is,

  $\text{Rate}\text{= k}\left[\text{alkylhalide}\right]\left[\text{nucleophile}\right]$

Nucleophile attacks the back side of leaving group in ${\text{S}}_{\text{N}}2$ reaction, this results the formation of inversion products. Order of the substrate that favored in ${\text{S}}_{\text{N}}1$ reaction is $1°>2°>3°$ .
