If phenol is treated with 3 moles of conc. HNO₃ in the presence of H₂SO₄, what will be the product?
Correct answer: D. picric acid
- A. o-nitrophenol
- B. p-nitrophenol
- C. o-nitrophenol and p-nitrophenol
- D. picric acid
Explanation
Picric acid: Correct answer-When phenol is treated with concentrated nitric acid in the presence of sulfuric acid, it undergoes nitration, leading to the formation of picric acid (2,4,6-trinitrophenol), which is the major product.

About Alcohols and Phenols
Alcohols are classified as primary, secondary or tertiary and studied through their hydrogen bonding, acidity, oxidation and reactions with active metals, acids and halogenating agents. Phenols require separate treatment because the hydroxyl group is attached to an aromatic ring, making their acidity and electrophilic substitution different from ordinary alcohols.
