- The melting point is low due to weak van der Waal’s forces of attractions between the covalent molecules.
- The force of attraction between the molecules of a covalent compound is very weak.
- Only a small amount of heat energy is required to break these weak molecular forces, due to which covalent compound have low melting points and low boiling points.
- Please note that some of the covalent solids like diamond and graphite have, however very high melting points and boiling points.
