Phenol br2 water
WebSolution Verified by Toppr Correct option is B) Bromination of phenol or its derivative can be done in the presnce of bromine water. Since OH is a strong activating group towards electropholic substitution reaction and is ortho-para directing. Thus Br will come at ortho and para of OH on the benzene ring.

Aldehydes will decolourise bromine water. The oxidation of aldehydes to acids is discussed in this answer Does Br2/H2O oxidize all aldehydes? In addition alpha-bromination of the aldehyde via the acid catalysed bromination of the enol is a well-documented process.
WebIf bromine water is added to phenylamine, the bromine water is decolourised and a white precipitate is formed. This is exactly like the reaction which happens with phenol. The precipitate is 2,4,6-tribromophenylamine. Notice the multiple substitution around the ring - into all the activated positions. (The 6- position is, of course, just the ...
