Question
Assertion: Acylation of amines gives a monosubstituted product whereas alkylation of amines gives polysubstituted product.
Reason: Acyl group sterically hinders the approach of further acyl groups.
Options
Both assertion and reason are wrong.
Both assertion and reason are correct statements but reason is not correct explanation of assertion.
Assertion is correct statement but reason is wrong statement.
Both assertion and reason are correct statements and reason is correct explanation of assertion.
