Question

Phenol forms $2,4, 6$-tribromophenol on treatment with $Br_{2}$ in carbon disulphide at $273 \,K$. Bromine polarises in carbon disulphide.

• A. Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
• B. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
• C. Assertion is true but Reason is false.
• D. Both Assertion and Reason are false.

Answer 1

The Correct Option is D

Phenol forms $2,4,6$ -tribromophenol on treatment with $Br _{2}$ in water. In $H _{2} O$ phenoxide ion is formed which highly activates it towards electrophilic substitution reaction.
