Chapter 22, Problem 22.17P

Interpretation Introduction

(a)

Interpretation:

The product formed on reaction of $1-\text{bromo}-2-\text{butanone}$ with pyridine is to be stated.

Concept introduction:

The nucleophilic substitution reactions are the reactions in which nucleophile attacks the electrophilic centre and eliminates another group. These 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.

Interpretation Introduction

(b)

Interpretation:

The product formed on reaction of $\alpha -\text{bromoacetophenone}$ with sodium acetate is to be stated.

Concept introduction:

The nucleophilic substitution reactions are the reactions in which one nucleophile is substituted by another nucleophile. These reactions depend upon the nucleophilicity and concentration of the nucleophile.

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

The ${\text{S}}_{\text{N}}\text{1}$ reaction is a nucleophilic substitution reaction in which the substitution of nucleophile takes place. This reaction takes place in two steps.
