Given below are two statement :

Statement I: Bromination of phenol in solvent with low polarity such as or requires Lewis acid catalyst.
Statement II : The lewis acid catalyst polarises the bromine to generate .
In the light of the above statements, choose the correct answer from the options given below :
  1. (A)Statement I is true but Statement II is false.
  2. (B)Both Statement I and Statement II are true
  3. (C)Both Statement I and Statement II are false.
  4. (D)Statement I is false but Statement II is true.✓ Correct

Answer: (D)

Solution

Phenol is a strongly activated aromatic ring, so it undergoes bromination directly with bromine even in a low-polarity solvent, without any Lewis acid catalyst; Statement I is false. However it is true in general that a Lewis acid catalyst polarises to generate ; Statement II is true. Hence I false, II true.
