Which one is the carbonyl protecting group?
Correct answer: B. Esters
- A. Carboxylic acid
- B. Esters
- C. Alcohol
- D. Amino Derivatives
Explanation
Esters are commonly used as protecting groups for carbonyl compounds. The carbonyl group (C=O) in aldehydes and ketones can be protected by converting them into esters. This prevents unwanted reactions at the carbonyl group while other reactions are carried out on the molecule.

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.
