Q. When o-or p-phenol sulphonic acid is treated with bromine water, the product formed is
A) 2, 4-dibromophenol
B) 2, 4, 6-tribromophenol
C) 3-bromophenol boric acid
D) 3, 5-dibromophenol
Explanation
(b)
Like nitration, bromination of o-or p-phenolsulphonic acid occurs with simultaneous replacement of $SO_{3}H$ group by Br atom to ultimately give 2, 4, 6-tribromophenol.
