Vedclass · Answer

(D) The preparation of an ester from a carboxylic acid and an alcohol is known as Fischer esterification. The reaction is reversible and is represented as: $RCOOH + R'OH \rightleftharpoons RCOOR' + H_2O$. To shift the equilibrium in the forward direction and increase the yield of the ester,a dehydrating agent is used to remove the water produced. Concentrated $H_2SO_4$ acts as both a catalyst and a dehydrating agent in this reaction.

In the preparation of an ester,the commonly used dehydrating agent is
