Question
Explain why covalent compounds have generally high melting points?
Advertisements
Solution
Covalent compounds are made up of electrically neutral molecules. So the force of attraction between the molecules is very weak. Only a small amount of heat energy is required to break these weak molecular forces, due to which covalent compounds have a low melting point.
