Question

A primary amine is formed from an amide by the treatment of bromine and alkali. The primary amine has (A) 1 carbon atom less than amide (B) 1 carbon atom more than amide (C) 1 hydrogen atom less than amide (D) 1 hydrogen atom more than amide

RCONH2+Br2+4KOH xrightarrowRNH2+2KBr +K2CO3 ∵ 1 C of amide is removed in form of K2CO3 ∴ Amine formed has one C atom less than amide.

1 carbon atom less than amide

1 carbon atom more than amide

1 hydrogen atom less than amide

1 hydrogen atom more than amide

$RCON H_{2} + B r_{2} + 4 K O H RN H_{2} + 2 K B r$ $+ K_{2} C O_{3}$ $∵$ 1 C of amide is removed in form of $K_{2} C O_{3}$ $∴$ Amine formed has one C atom less than amide.
