Phenol is heated with a solution of mixture of KBr and KBrO ₃ . The major product obtained in the above reaction is

Options

  1. A3-Bromophenol
  2. B4-Bromophenol
  3. C2, 4, 6- Tribromophenol
  4. D2-Bromophenol

Correct answer

C. 2, 4, 6- Tribromophenol

Step-by-step solution

In acidic medium, KBr + KBrO ₃ in turn produces Br ₂ . Phenol reacts with Br ₂ (aq) to give 2, 4, 6 trinitrophenol
