Chapter 21, Problem 21.25P

Interpretation Introduction

(a)

Interpretation:

The general structure of the alcohols which are obtained by the reaction of Grignard reagents of the form $\text{RMgBr}$ with ethyl formate 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. It is of two types, ${\text{S}}_{\text{N}}\text{1}$ and ${\text{S}}_{\text{N}}\text{2}$.

Grignard reagent is a reagent which acts as a nucleophile to attack the electron deficient atoms. Grignard reagent contains a metal along with a negatively charged alkyl group.

Interpretation Introduction

(b)

Interpretation:

The synthesis of $3-\text{pentanol}$ from ethyl formate and a Grignard reagent is to be stated.
