Chapter 13, Problem 4Q

Interpretation Introduction

Interpretation:

The given structure that is not a resonance hybrid is to be determined.

Concept introduction:

$\text{Sn}1$ is aunimolecular substitution reaction and is also called a nucleophilic substitution reaction. The order of the reaction is oneand rate of the reaction depends only on the reactant molecule

In $\text{Sn}1$ reaction, the formation of carbocation takes place. $\text{Sn}1$ reaction gives two products. One is retention of stereochemistry and the other is inversion of stereochemistry.

In $\text{Sn1}$ reaction, the bond between the carbon and the leaving group breaks first. Separation of the leaving group from the carbon generates a carbocation. The nucleophile attacks the electrophilic carbocation to form a bond.
