Question

A compound A has a molecular formula C7H7NO. On treatment with Br2 and KOH, A gives an amine B which gives carbylamine test. B upon diazotisation and coupling with phenol gives as azodye. A can be (A) C6H5CONHCH3 (B) C6H5CONH2 (C) C6H5NO (D) o, m- or p-C6H4(NH2)CHO

Tardigrade Admin · Accepted Answer

Correct answer is (b) C6H5CONH2

Q. A compound A has a molecular formula $C_{7} H_{7} NO$ . On treatment with $B r_{2}$ and KOH, A gives an amine B which gives carbylamine test. B upon diazotisation and coupling with phenol gives as azodye. A can be

$C_{6} H_{5} CON H C H_{3}$

$C_{6} H_{5} CON H_{2}$

$C_{6} H_{5} NO$

$o, m - or p - C_{6} H_{4} (N H_{2}) C H O$

Correct answer is (b) $C_{6} H_{5} CON H_{2}$
