Verified by Toppr

The esterification reaction can be catalyzed by the presence of an acid or a base.

Also, during the reaction, a carboxylic acid reacts with an alcohol to form an ester. A molecule of water is also eliminated.

Sulphuric acid catalyzes the reaction and also acts as a dehydrating agent.

Option D is correct.
