Question

Assertion (A): Acetanilide is less basic than aniline.
Reason (R): Acetylation of aniline results in decrease of electron density on nitrogen.

• A. Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
• B. Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).
• C. Assertion (A) is true, but Reason (R) is false.
• D. Assertion (A) is false, but Reason (R) is true.

Hint:

When studying basicity, remember that electron-withdrawing groups (like acetyl) decrease electron density on nitrogen, lowering basicity.

Answer 1

The Correct Option is A

Acetanilide exhibits lower basicity than aniline. This is attributed to the acetyl group's electron-withdrawing effect via resonance, which reduces the nitrogen atom's availability for protonation. Consequently, acetanilide's reduced basicity is explained by this phenomenon, confirming both the statement and its justification, with the justification accurately elucidating the statement.
