Question

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\mathrm{S_8} while oxygen exists as O2\mathrm{O_2}. Reason (R): Oxygen forms pπpπ\mathrm{p\pi - p\pi} 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:

Options
  1. a

    (A) is correct but (R) is not correct

  2. b

    (A) is not correct but (R) is correct

  3. c

    Both (A) and (R) are correct and (R) is the correct explanation of (A)

  4. d

    Both (A) and (R) are correct but (R) is not the correct explanation of (A)

Correct Answera

(A) is correct but (R) is not correct

Detailed Solution

Strategy: Correlate group 15 elements with their specific properties or reactions.

Step 1: Property Analysis Recall trends in acidic character of oxides, stability of hydrides, or allotropic forms in the nitrogen family.

Step 2: Selection Matching the correct property or product identified in the options provides the answer.
