D Sharing Formation of water is a covalent bond which involves the sharing of electrons between two reacting atoms so that both can attain the stable octet structure
Hydrogen Bonding occurs when the hydrogen atom of one molecule is bonded with a molecule of high electronegativity element like nitrogen of another molecule.
It is a type of dipole-dipole interations.
The nitrogen is a highly electronegative element that forms a weakbond with the hydrogen atom of another molecule with dipole-dipoleinteraction.
Hydrogen bonds are weaker than covalent and ionic bonds.
