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 S 8 ​ while oxygen exists as O 2 ​ . Reason (R) : Oxygen forms p π − p π 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 :

TestHub · Accepted Answer

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