Assertion (A) Acylation of amines gives a monosubstituted product whereas alkylation of amines gives polysubstituted product.
Reason (R) Acyl group sterically hinders the approach of further acyl groups.
Assertion (A) Hofmann's bromamide reaction is given by primary amines.
Reason (R) Primary amines one more basic than secondary amines.
Assertion (A) N-ethylbenzene sulphonamide is soluble in alkali.
Reason (R) Hydrogen attached to nitrogen in sulphonamide is strongly acidic.
