An organic compound (A) with molecular formula `C_(7)H_(8)O` dissolves in NaOH and gives characteristic colour with `FeCI_(3)`. On treatement with `Br_(3)`, it gives a tribromo product `C_(7)H_(5)Br_(3)`. The compound is:

A

p-Hydroxybenzene

B

2-Methoxy-2-phenyl propane

C

m-Cresol

D

p-Cresol

Text Solution

Verified by Experts

The correct Answer is:
C

Four DU in A and `(C:H~~1:1)` suggest benzene ring with one extra C atom. Reactivity with NaOH and `FeCI_(3)` suggests (A) to be a phenol. The formation of a tribrommo product suggest that o- and p-positions are vacantg. So methyl group should be present at m-position. Hence, (A) is m-cresol.
