Assertion(A) Acylation of amines gives a monsubstituted product whereas alkulation of amines gives polysubstitues product.
Reason(R ) Acyl group sterically hinders the apprach of further acyl group

A

Both assertion and reason are wrong.

B

Both assertion and reason are correct statements but reason is not correct explanation of assertion.

C

Assertion is correct statement but reason is wrong statement.

D

Both assertion and reason are correct statements and reason is correct explanation of assertion.

Text Solution

Verified by Experts

The correct Answer is:
C
Correct reason. Due to delocalization of the lone pair of electrons of the N-atom over the carbonyl group in the acyl derivative, the electron density on the N-atom decreases to such an extent that it does not act as a nucleophile at all and hence does not react with another molecule of the acylating agent.

Tertiary amines do not undergo acylation. Give reason.

(a) If both the assertion and reason are true and reason is a true explanation of the assertion. (b) If both the assertion and reason are true but the reason is not the correct explanation of assertion. (c) If the assertion is true but reason is false. (d) If assertion is false but reason is true. Q. Assertion: Oxidation of 1-nitronaphthalene gives o-nitrophthalic acid whereas 1-amino naphthalene on oxidation gives phthalic acid. Reason: An amino group attached to the benzene ring makes it resistant to oxidation whereas nito group makes the benzene ring susceptible to oxidation.
