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

Answer: (D)

Solution

With excess bromine water the phenol is brominated at the positions activated by the group, and at the carbon already bearing the sulphonic acid group the incoming bromine displaces in an ipso substitution. The outcome is the brominated phenol in which bromine occupies the ortho and para positions, including the site vacated by the sulphonic acid group.
