  1. (A)(see structure)
    ✓ Correct
  2. (B)(see structure)
  3. (C)(see structure)
    ✓ Correct
  4. (D)(see structure)

Answer: (A), (C)

Solution

Phenol reacts with bromine water to give tribromophenol as the major product due to the strong activating effect of the –OH group, which directs bromination to ortho and para positions. In bromine water (aqueous medium), all three positions (2 ortho + 1 para) get brominated. Options A and C show brominated phenol products that would form in this reaction.
