Detailed explanation-1: -The hydrogen bond has justifiably been termed the ‘master key of molecular recognition’. It is an interaction that is weaker than the covalent bond and stronger than the van der Waals interaction.
Detailed explanation-2: -The Hydrogen bonds are the weakest as they aren’t really bonds but just forces of attraction to the dipoles. On a hydrogen atom which are permanent and bonded to two atoms which are highly electronegative in nature. They are just electrostatic and not an actual physical bond which makes them very easy to simply bypass.
Detailed explanation-3: -The hydrogen bond (5 to 30 kJ/mole) is stronger than a van der Waals interaction, but weaker than covalent or ionic bonds. This type of bond can occur in inorganic molecules such as water and in organic molecules like DNA and proteins.
