Question

Assertion : Phenol forms $2$, $4$, $6$-tribromophenol on treatment with $Br_2$ in carbon disulphide at $273\, K$.
Reason : Bromine polarises in carbon disulphide.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (D)

Phenol forms $2,4,6$ tribromophenol on treatment with $Br _{2}$ in water. Phenol forms a mixture of ortho and para bromophenol on treatment with $Br _{2}$ in carbon disulphide Bromine does not polarises in carbon disulphide.
