JEE Main 2024p Block Elements (Group 15, 16, 17 & 18) Question with Solution

JEE Main 2024 (09 Apr Shift 1)

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 , which is not possible for sulphur. In the light of the above statements, choose the most appropriate answer from the options given below :

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

Step-by-step explanation

Oxygen can form multiple bond with itself due to its small size while sulphur cannot form multiple bond with itself as bond will be unstable due to large size of sulphur, but sulphur can form multiple bond with small size atom like and . $\begin{aligned} & \text { eg. } \mathrm{S}=\mathrm{C}=\mathrm{S} \\ & \mathrm{S}=\mathrm{C}=\mathrm{N}^{-} \leftrightarrow \mathrm{S}^{\ominus}-\mathrm{C} \equiv \mathrm{N} \end{aligned}$
