Given below are tow statement : Statement I : Bromination of phenol in solvent with low polarity such as CHCl₃ or CS₂ requires Lewis acid catalyst. Statement II : The Lewis acid catalyst polarises the bromine to generate Br⁺. In the light of the above statements, choose the correct answer from the options given below : (1) Statement I is true but Statement II is false. (2) Both Statement I and Statement II are true. (3) Both Statement I and Statement II are false. (4) Statement I is false but Statement II is true.

1. Statement I is true but Statement II is false.
2. Both Statement I and Statement II are true.
3. Both Statement I and Statement II are false.
4. Statement I is false but Statement II is true.

Correct answer: Statement I is false but Statement II is true.

Solution

Statement I is incorrect because bromination of phenol in low polarity solvents does not require a Lewis acid catalyst; the reaction can occur without it. However, Statement II is accurate as the Lewis acid can indeed polarize bromine to form Br⁺, facilitating the electrophilic substitution.
