[AIEEE 2006] Which structure, on treatment with bromine water, gives a tribromo derivative?

(A)A cresol-type ring bearing a free phenolic –OH and a methyl groupCorrect
(B)An analogous ring with –CH₂OH in place of the free phenolic –OH
(C)A positional isomer of (A) with the free –OH differently placed on the ring
(D)A ring bearing only –CH₂OH, with no free ring –OH at all

Answer: (A)

Solution

Instant, exhaustive bromination with bromine water to a tribromo precipitate is a hallmark qualitative test specific to compounds bearing a free phenolic –OH (strongly
