Question

why melting and boiling point of O2 is drastically lower than sulphur​

Answer 1

Answer:

Oxygen is gas due to which the molecules are loosely bonded due to which less energy(heat) is required to break the molecules. Hello buddy, ... - O2 shows weak van der waal forces between the molecules and thus has low melting and boiling points. - At room temperature, sulphur exists as polyatomic molecule S8.

Explanation:

This is ur ans....hope it helps :)

Answer 2

Explanation:

While Oxygen having a smaller size has electron cloud closer to the nucleus and cloud movement is restricted . Therefore it has weak temporary dipoles. Hence sulphur having strong forces of attraction will have higher melting and boiling points compared to oxygen.

Melting and boiling point depends on the intermolecular forces of attraction between the molecules. ... Due to which Sulphur having stronger intermolecular forces has higher melting point and boiling point than oxygen with weaker intermolecular forces.

Hope this helps mate ☺️.
