WebA hydrogen bond can be defined as an electrostatic force between a hydrogen atom and another chemical element which leads to sharing of electrons (lone pairs) between … WebAs a result, hydrogen bonding rises in the water molecules because of the dipole-dipole interactions among oxygen atoms and hydrogen atoms. According to the experts, the hydrogen bonding is mostly strong when compared to the normal dispersion and dipole-dipole forces; however, it appears to be weak if compared to ionic bonds or true …
Web2 dec. 2024 · Hydrogen bonds are very strong compared to other dipole-dipole interactions, but still much weaker than a covalent bond. A typical hydrogen bond is about \(5\%\) as strong as a covalent bond. Hydrogen bonding occurs only in molecules where hydrogen is covalently bonded to one of three elements: fluorine, oxygen, or nitrogen.
