Chapter 12, Problem 34P

Interpretation Introduction

Interpretation: The class of alcohol that will be formed on reaction with excess Grignard reagent followed by addition of dilute acid has to be found.

Concept Introduction:

Grignard reagent: Alkyl, vinyl, or aryl-magnesium halides are called as Grignard reagents.

The chemical formula of the Grignard reagent is $\text{RMgX}$.

$\begin{array}{l}\text{Where}\\ \text{R-}\text{Alkyl}\text{or}\text{aryl or}\text{vinyl}\\ \text{X}\text{-}\text{Halogens}\text{such}\text{as}\text{Br,Cl}\text{or}\text{I}\end{array}$

Reaction of ester with Grignard reagent:

Ester reacts with excess Grignard reagent followed by addition of dilute acid and forms tertiary alcohol as the product as shown in the general scheme.
