Interpretation Introduction

Interpretation:

A curve arrow mechanism for the given reaction is to be stated and the two structural reasons as to why the equilibrium lies to the right are to be stated.

Concept introduction:

The nucleophilic substitution reactions depend upon the nucleophilicity and concentration of the nucleophile.

The ${\text{S}}_{\text{N}}2$ reaction is a nucleophilic substitution bimolecular single step reaction in which the addition of nucleophile and removal of leaving group takes place simultaneously.

The ${\text{S}}_{\text{N}}1$ reaction is a nucleophilic substitution reaction in which the substitution of nucleophile takes place. This reaction takes place in two steps. There is generation of carbocation in the first step and in the second step the nucleophile attacks at the carbocation for the corresponding product.
