A compound A has a molecules formula `C_(7)H_(7)NO`. On tratement with `Br_(2) and KOH_(4)` , A gives amine B which gives, carbylamine test. B upon diazotisation and coupling with give an azo dye. A can be

A

`C_(6)H_(5)CONHCOCH_(3)`

B

`C_(6)H_(5)CONH_(2)`

C

`C_(6)H_(5)CONH_(2)`

D

`o-, m- or p - C_(6)H_(4)(NH_(2))CHO`

Text Solution

Verified by Experts

The correct Answer is:
B
`underset((C_(7)H_(7)NO))(A)overset(Br_(2)//KOH)rarrunderset("(amine)")(B)overset("i) diazotisation")underset("ii) coupling with phenol")rarr"Azo dye"`
Given reactions indicate B as `1^(@)` aromatic amine, and A as an aromatic amide, `C_(6)H_(5)CONH_(2)`
