Chapter 15, Problem 15.23P

Interpretation Introduction

(a)

Interpretation:

The products formed by the reaction of $\text{1, 3-butadiene}$ with $\text{HCl}$ are to be predicted with the help of the reaction mechanism.

Concept introduction:

Conjugated dienes give two types of addition products-$1,2-$ addition and $1,4-$ addition products. The addition product $1,2$ indicates the addition of hydrogen halide at adjacent carbon and also, it is the major product. The addition product $1,4$ indicates the addition of hydrogen halides to carbons that have a $1,4$ relationship and also, it is the minor product.

Interpretation Introduction

(b)

Interpretation:

The products formed by the ${\text{S}}_{\text{N}}1$ solvolysis of $\text{3-chloro-1-methylcyclohexene}$ in ethanol are to be predicted with the help of the reaction mechanism.

Concept introduction:

When the solvent in ${\text{S}}_{\text{N}}1$ reaction acts as a nucleophile, then the reaction is known as solvolysis reaction. In this reaction, carbon–halogen bond gets break down which results in the formation of carbocation.
