Question

The number of functional groups present in the following compound is :-

• A. 5
• B. 7
• C. 6
• D. 8

Answer 1

Answer: (D)

8

Answer 2

The functional groups present in the compound are:

1. Aldehyde: The terminal group H-C=O.
2. Amine: The -NH₂ group.
3. Ketone: There are three carbonyl groups (C=O) that are not part of an amide, ester, or carboxylic acid.
4. Amide: The -C(=O)-NH- linkage.
5. Ester: The linkage -CH-O-CH₂-C(=O)-OH.
6. Carboxylic acid: The terminal group -C(=O)-OH.

Counting these distinct functional groups: 1 (Aldehyde) + 1 (Amine) + 3 (Ketones) + 1 (Amide) + 1 (Ester) + 1 (Carboxylic acid) = 8 functional groups.
