Question:medium
Assertion (A): Acetanilide is less basic than aniline.
Reason (R): Acetylation of aniline results in decrease of electron density on nitrogen.
Assertion (A): Acetanilide is less basic than aniline.
Reason (R): Acetylation of aniline results in decrease of electron density on nitrogen.
Reason (R): Acetylation of aniline results in decrease of electron density on nitrogen.
Show Hint
When studying basicity, remember that electron-withdrawing groups (like acetyl) decrease electron density on nitrogen, lowering basicity.

- Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
- Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).
- Assertion (A) is true, but Reason (R) is false.
- Assertion (A) is false, but Reason (R) is true.
Show Solution
The Correct Option is A
Solution and Explanation
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.
