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 … WebAbstract Hydrogen bonds are a key feature of chemical structure and reactivity. Recently there has been much interest in a special class of hydrogen bonds called “strong” or “low-barrier” and characterized by great strength, short distances, a low or vanishing barrier to hydrogen transfer, and distinctive features in the NMR spectrum. Although the energy of …
