Question

why are dioxygen a gas but sulphur a solid

Answer 1

hey dear here is ur answer ________

☆ Becoz O2 is smaller in size as compare to sulphur, and also the intermolcular force between O2 is very weak , which cause as to exist as a gas. on other hand sulphur does not formed M2 types molecule so they are in puckered structer held together by strong co- covalent bond , hence it is solid.

Answer 2

Hey !!

It is because of its small size, oxygen is capable of forming pπ - pπ bond and exists as diatomic O₂ molecule. The intermolecular forces in oxygen are weak van der Waals force, due to which it is a gas at room temperature. On the other hand, sulphur, due to its larger size prefers to form S - S single bond and exist as octaatomic S₈ molecule puckered ring structure. Because of larger size the force of attraction holding the S₈ molecules together are much stronger. Hence sulphur is a solid at room temperature.
