Chapter 10, Problem 10.43P

Interpretation Introduction

(a)

Interpretation:

The product for the given reaction with detailed mechanism is to be drawn.

Concept introduction:

The methyl esters can be prepared from carboxylic acid when it is reacted with diazomethane. The negatively charged oxygen of the carboxylate ion formed by the deprotonation of carboxylic acid acts as a nucleophile, and the reaction proceeds via ${\text{S}}_{\text{N}}\text{2}$ mechanism. The carbon atom of diazomethane gets converted to an electron-poor site by protonation.
