Question

Define simply,,,,,,why do covalent compounds have low melting and boiling points??????

Answer 1

 They have weak intermolecular forces, that is to say, the forces between molecules is very weak. The consequence of this, is that it becomes easy to move individual molecules away from other molecules as the bonding between molecules is weak, hence it needs little energy to break. Since temperature is proportional to energy, that means the temperature required to melt the compound is low.

Covalently bonded molecules are seen to have strong bonds within the molecule, but inter molecular forces are small. This gives rise to low melting and boiling point.
