Detailed explanation-1: -In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.

Detailed explanation-2: -Water can form four hydrogen bonds. The two lone pairs of oxygen atoms and the two hydrogen atoms of water are involved in intermolecular hydrogen bonding.

Detailed explanation-3: -van der Waals Bonding Water molecules in liquid water are attracted to each other by electrostatic forces, and these forces have been described as van der Waals forces or van der Waals bonds.

Detailed explanation-4: -In chemistry, a hydrogen bond (or H-bond) is a primarily electrostatic force of attraction between a hydrogen (H) atom which is covalently bound to a more electronegative “donor” atom or group (Dn), and another electronegative atom bearing a lone pair of electrons-the hydrogen bond acceptor (Ac).
