The work of conc.H2SO4 in esterification process is as:
Correct answer: A. Dehydrating agent and catalyst
- A. Dehydrating agent and catalyst
- B. Hydrolyzing agent
- C. Dehydrating agent
- D. Catalyst
Explanation
Concentrated sulfuric acid serves two purposes in Fischer esterification. It acts as an acid catalyst to protonate the carbonyl oxygen, making it more electrophilic. It also acts as a dehydrating agent, removing the water produced to shift the equilibrium towards the ester product.

About Carboxylic Acids
Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
