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 because the acetyl group reduces electron density at the nitrogen via resonance, thereby hindering its protonation. Consequently, both the statement and its justification are accurate, with the justification providing a correct explanation for the statement.
