Question

A compound X on treatment with Br2 and KOH gives an amine Y. Y gives carbylamine reaction. Y upon diazotisation and coupling with phenol gives an azodye. X can be:

Answer 1

Compound X is C6H5CONH2.

C6H5CONH2 + Br2 + KOH ----> C6H5-NH2 ( Y)
C6H5-NH2 + CHCl3 + 3KOH-----> C6H5-NC

C6H5-NH2 + NaN02 + HCl ---> C6H5N2Cl

C6H5N2CL + C6H5OH + OH- ----> Azodye


Hope you get your answer.
