A compound X has the molecular formula `C_(7)H_(7)NO`. On treatment with `Br_(2)` and KOH. X gives an amine Y. The latter gives carbylamine test. Y upon diazotisation and coupling with phelon gives an azo dye. Thus X is

A

`PhCONH_2`

B

`PhCONHCOCH_3`

C

`PhNO_2`

D

`PhCOONH_4`

Text Solution

Verified by Experts

The correct Answer is:
A
Reaction of (X ) with ` Br_2 + KOH` suggests theat (X ) is an amide . Carbulamine test and cou,oing reaction fo (Y) suggest that (Y) is `1^@` aromatic amine .
