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 ( S ₈ ) while oxygen exists as ( O ₂ ). Reason (R) : Oxygen forms ( p - p ) 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 statemen

Options

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

Correct answer

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

Step-by-step solution

Oxygen can form 2 p -2 p multiple bond with itself due to its small size while sulphur cannot form multiple bond with itself as 3 p -3 p bond will be unstable due to large size of sulphur, but sulphur can form multiple bond with small size atom like C and N . aligned & eg. S = C = S & S = C = N ⁻ S ^ - C N aligned
