Question

Assertion :Pyridine is more basic than piperidine. Reason: N atom is ${sp}^2$-hybridised in both.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
• C. Assertion is correct but Reason is incorrect.
• D. Both Assertion and Reason are incorrect.

Answer 1

The correct option is D Both Assertion and Reason are incorrect.

REF. Image :(I) (piperidine) is more basic than pyridine

REF. Image : (II) Although there is no delocalisation of LP ${\overline{e}}^{\prime }s$ of N atom in both.

But N is $s{p}^3$-hybridised in (I) and $s{p}^2$-hybridised in (II).

So (I) is more basic than (II).

Option D is correct.
