(A) : Carbylamine reaction involves chemical reaction between primary amines, chloroform in basic medium. (R ) : In carbylamine reaction -NH_(2) group changes into -NC group.

Assertion (A): Hofmann's bromamide reaction is given by primary amines. Reason: Primary amines on more basic than secondary amines.

Assertion (A): Hofmann's bromamide reaction is given by primary amines. Reason: Primary amines on more basic than secondary amines.
