JEE MAIN - Chemistry (2024 - 9th April Morning Shift - No. 14)

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 $$\mathrm{S}_8$$ while oxygen exists as $$\mathrm{O}_2$$.

Reason (R) : Oxygen forms $$p \pi-p \pi$$ multiple bonds with itself and other elements having small size and high electronegativity like $$\mathrm{C}, \mathrm{N}$$, which is not possible for sulphur.

In the light of the above statements, choose the most appropriate answer from the options given below :

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

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

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

Both $$(\mathbf{A})$$ and $$(\mathbf{R})$$ are correct and $$(\mathbf{R})$$ is the correct explanation of $$(\mathbf{A})$$

Explanation

Oxygen exists as $$\mathrm{O}_2$$

Sulphur exists as $$\mathrm{S}_8$$

Because of small size of oxygen, oxygen can form $$2 \mathrm{p}_\pi-2 \mathrm{p}_\pi$$ bond.

$$\Rightarrow$$ Assertion (A) is correct.

$$\Rightarrow$$ Reason (R) is correct.

Reason (R) is correct explanation of Assertion (A).
