Which from following compounds is obtained when phenol reacts with dilute nitric acid at low temperature?

Options

  1. Ao-Nitrophenol only
  2. Bp-Nitrophenol only
  3. C2,4,6-trinitrophenol
  4. DMixture of ortho and para nitrophenols

Correct answer

D. Mixture of ortho and para nitrophenols

Step-by-step solution

Phenol undergoes electrophilic aromatic substitution with dilute nitric acid at low temperature. The hydroxyl group activates the ring and directs substitution to ortho and para positions. Phenol + Dilute HNO ₃ Low temperature o-Nitrophenol + p-Nitrophenol Mild conditions prevent further nitration. Option A and B are incomplete, while Option C requires concentrated nitric acid. The correct product mixture corresponds to Option D. The final answer is D .
