WebIt is because of such weaker forces, which fail to make the compound bind tightly. Since the forces are weak, it needs only a little amount of energy to break. Heat is a form of energy. Since lower heat (energy) is capable of breaking these weak intermolecular forces. As a result, the covalent compounds have low melting and boiling points. WebCovalently bonded substances may consist of small molecules, such as H2, Cl2, O2, N2, HCl, H2O, NH3, and CH4. Some covalently bonded substances have giant covalent structures, such as diamond.
