Picric acid is_________________?
Correct answer: D. none of these
- A. monocarboxylc acid
- B. dicarboxylic acid
- C. aromatic carboxylic acid
- D. none of these
Explanation
Picric acid is 2,4,6-trinitrophenol, so it contains a phenolic -OH group and nitro groups, but no carboxyl group. It is therefore not a mono-, di- or aromatic carboxylic acid, making none of these the best option. The likely mistake is selecting aromatic carboxylic acid because picric acid has an aromatic benzene ring.

About Phenols
Phenols contain a hydroxyl group directly bonded to an aromatic ring, making them more acidic than alcohols because the phenoxide ion is resonance-stabilised. Reactions include ionisation with bases, electrophilic substitution, bromination, nitration and oxidation, with attention to the difference between phenols and aliphatic alcohols.
