WebAlthough the energy of an ordinary hydrogen bond is ca 5 kcal mol-1, the strength of these hydrogen bonds may be > or = 10 kcal mol-1. The properties of these hydrogen bonds have been investigated by many experimental techniques, as well as by calculation and by correlations among those properties. WebWhy Covalent bond is stronger than hydrogen bond? We know that the bond energy of hydrogen bonding is very less as compared to that of covalent bond (bond energy of hydrogen bonding is 8-42 KJ/mole and covalent bond is 200 KJ/mole). Also the covalent bond has shorter bond length in comparison to the hydrogen bond (it has quite longer …
