Chapter 9, Problem 9.14P

Interpretation Introduction

Interpretation:

The explanation as to why no reaction occurs between methyl bromide and ethanol at ${\text{25 }}^{\text{ο}}\text{C}$ while a good yield of ethyl methyl ether is obtained when an excess of sodium ethoxide added 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 incoming nucleophile.

The ${\text{S}}_{\text{N}}\text{2}$ reaction is a nucleophilic substitution bimolecular reaction in which the addition of incoming nucleophile and removal of existing nucleophile takes place simultaneously. The rate of reaction depends upon both the substrate and reactant in the rate law equation.
