Phenol is heated with a solution of mixture of `KBr` and `KBrO_(3)`. The major product obtained in the above reaction is

Options

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

Answer

D

Explanation

`Br_(2)` is formed by a redox reaction
`5Br^(-)+BrO_(3)^(-) +6H^(+)rarr 3Br_(2)+3H_(2)O`
`-OH` group is the activating group and there is `S_(E)` at o-and p-positions giving yellowish white precipitate of 2, 4, 6-tribromophenol
