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 is less basic than aniline because the acetyl group withdraws electron density from the nitrogen through resonance, making the nitrogen less available for protonation. This explains why acetanilide is less basic. Hence, both the assertion and the reason are true, and the reason correctly explains the assertion.
