The `pK_a` value of (I) is more than the `pK_a` value to (II).
Nonaromatic compounds are more stable than anti-aromatic compounds.

A

If both (A) and ( R) are true and ( R) is the correct explanation of (A).

B

If both (A) and ( R) are true but ( R) is not correct explanation of (A).

C

If (A) is true but ( R) is false.

D

If (A) is false but ( R) if true.

Text Solution

Verified by Experts

The correct Answer is:
A
(a) Conjugate base of `(I)` and `(II)` are :

Stability and acidic order : aromatic gt nonaromatic gt anti-aromatic.
`(I)` is stronger acid than `(II)`, hence `(I)` has lower `pK_a`.
