When phenol is heated with concentrated nitric acid, the product is ?
Correct answer: A. Picric acid
- A. Picric acid
- B. o-Nitrophenol
- C. 1,3,5-Trinitrobenzene
- D. p-Nitrophenol
Explanation
When phenol is heated with concentrated nitric acid (HNO3), the product is not 1,3,5-trinitrobenzene.The reaction between phenol and concentrated nitric acid typically results in the formation of 2,4,6-trinitrophenol, also known as picric acid. Picric acid is produced through the nitration of phenol, where nitro groups (-NO2) are introduced into the phenol molecule.

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.
