Question

Phenol is heated with a solution of a mixture of $KBr$ and $KBr{O}_3$. The major product obtained in the above reaction is:

• A. $2$-bromophenol
• B. $3$-bromophenol
• C. $4$-bromophenol
• D. $2,4,6$-tribromophenol

Answer 1

The correct option is D $2,4,6$-tribromophenol

`$5KBr$ $+KBr{O}_3+3H_{2}O\to 3B{r}_2+6KOH$

This is one method for the preparation of $B{r}_2$.

Phenols undergo electrophilic substitution easier than benzene.

Hence, the correct option is $\text{D}$
