When carboxylic acids are heated with alcohol in the presence of concentrated H2SO4, the conversion of functional group takes place from:
Correct answer: B. Carboxyl group to an ester group
- A. Carboxyl to carbonyl group
- B. Carboxyl group to an ester group
- C. Carbonyl to carboxyl group
- D. Carboxyl to hydroxyl group
Explanation
This reaction is known as Fischer esterification, where the carboxyl group (-COOH) of a carboxylic acid reacts with an alcohol to form an ester (-COO-).

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.
