Phenol on treatment with dil. HNO3 at low temperature gives:
Correct answer: D. Both A and C
- A. o-Nitrophenol
- B. m-Nitrophenol
- C. p-Nitrophenol
- D. Both A and C
Explanation
The nitration of phenol with dilute nitric acid is a moderated electrophilic substitution. The -OH group is an ortho-, para- director, so the reaction produces a mixture of the ortho- nitrophenol and para-nitrophenol isomers.

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.
