Reason

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  while oxygen exists as .

Reason (R): Oxygen forms  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:

Canvas Classes · Accepted Answer

Assertion (A): Rhombic () and monoclinic () sulphur both consist of  crown-shaped rings. Oxygen exists as diatomic . ✓

Reason (R): Oxygen has small size and high electronegativity, enabling effective p–p overlap to form O=O double bonds. Sulphur has larger atomic size, so p–p overlap is poor — sulphur cannot form stable S=S double bonds and instead forms  rings with single S–S bonds. ✓

R correctly explains why O forms  while S forms .
