Question

Why there is a large difference between the melting and boiling point of oxygen and sulphur?

Answer 1

Oxygen is gas due to which the molecules are loosely bonded due to which less energy(heat) is required to break the molecules.

Sulfur exist in solid state as a non-metal since it is solid the molecules are tightly bonded therefore high amount of energy(heat) is required to break the molecules. Therefore oxygen have low melting point as compare to sulfur

Answer 2

Hello buddy,

● Why oxygen and sulphur show large difference in melting and boiling point ?
- At room temperature, oxygen exists as diatomic molecule O2.
- 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.
- S8 has packed ringed structure with strong covalent bonds between the molecules, thus it has high melting as well as boiling point.

Hope this helps you...
