Both Assertion & Reason are true and the reason is the correct explanation of the assertion.

Vedclass · Answer

(A) Oxygen exists as a diatomic molecule $(O_2)$ due to its small size and ability to form $p\pi-p\pi$ multiple bonds. Sulfur exists as a polyatomic puckered ring structure $(S_8)$ due to its larger size and inability to form stable $p\pi-p\pi$ multiple bonds.The large difference in the molecular size and the strength of van der Waals forces between $O_2$ (small,weak forces) and $S_8$ (large,stronger forces) leads to a significant difference in their melting and boiling points.Therefore,both the Assertion and the Reason are true,and the Reason correctly explains the Assertion.

Assertion : There is a large difference between the melting and boiling points of $O$ and $S$.
Reason : It can be explained on the basis of their atomicity in $O_2$ and $S_8$ molecules.
