INTERMOLECULAR FORCES are the forces between the atoms of matter.
Ion-dipole forces are the forces responsible for the solvation of ionic compounds in aqueous solutions, and are the strongest of the intermolecular foces. Hydrogen bonding is the second strongest intermolecular force, followed by dipole-dipole interactions. Related questions. How do intermolecular forces differ from attraction between ions? What is the strongest intermolecular force of attraction?Dipole-dipole forces are intermolecular forces that from between polar molecules. Because there is a separation of charges throughout the molecule, the negative part can attract a positive part of another molecule and visa verse. This is a relatively weak force and it only releases about 5 kJ/mol of energy when broken.

Dipoles are stronger than London Forces alone, so polar molecules tend to have stronger intermolecular forces than nonpolar molecules of a similar size and polarity. Hydrogen Bonds are a special type of dipole forces, in which a hydrogen atom is covalently bound to a very electronegative atom (N, O, F), resulting in a large dipole.
