Question

Given below are two statements: one is labelled as Assertion A and, the other is labelled as Reason R.
Assertion A: [6] Annulene, [8] Annulene and cis-[10] Annulene, are respectively aromatic, not-aromatic and aromatic.

Reason R: Planarity is one, of the requirements of aromatic systems.
In the light of the above statements, choose the most appropriate answer from the options given below.

• A. Both A and R are correct but R is NOT the correct explanation of A
• B. A is correct but R is not correct
• C. Both A and R are correct and R is the correct explanation of A
• D. A is not correct but R is correct

Answer 1

The correct option is D A is not correct but R is correct

$\left[6\right]$ Annulene is aromatic because it is planar, conjugated and follows Huckle's rule
$\left[8\right]$ Annulene and $\left[10\right]$ Annulene are both not aromatic because they are not planar. So,
Assertion (A) is not correct.
Reason (R) is correct because planarity is one of the requirements of aromatic system.
