Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : Both rhombic and monoclinic sulphur exist as S8 while oxygen exists as O2. Reason (R) : Oxygen forms πr-πr multiple bonds with itself and other elements having small size and high electronegativity like C, N, which is not possible for sulphur. In the light of the above statements, choose the most appropriate answer from the options given below :

1. Both (A) and (R) are correct and (R) is the correct explanation of (A).
2. Both (A) and (R) are correct but (R) is not the correct explanation of (A).
3. (A) is correct but (R) is not correct.
4. (A) is not correct but (R) is correct.

Correct answer: (A) is correct but (R) is not correct.

Solution

The assertion is accurate as both rhombic and monoclinic sulfur exist as S8, while oxygen is diatomic as O2. However, the reason is incorrect because it does not explain the existence of sulfur in the same molecular form; rather, it discusses bonding characteristics that do not directly relate to the assertion.
