Intermolecular forces are the interactions that exist between molecules. Hydrogen bond typically occurs when a hydrogen atom bonded to O, N, or F, is electrostatically attracted to a lone pair of electrons on an O, N, or F in another molecule. Polarizability is a measure of how the electron cloud around an atom responds to changes in its electronic environment. London forces, also known as dispersion forces are weak interactions caused by the momentary changes in electron density in a molecule. Dipole-dipole are the attractive forces between the permanent dipoles of two polar molecules. All compounds exhibit van der Waal forces.

Explanation:

Molecules interact each other by intramolecular forces. Among them are van der Waal forces, which are weak interactions, so all compounds interacts by this kind of forces. London forces (dispersion forces) are comprised in the group of van der Waal forces, so they are weak forces. Hydrogen bond is a stronger force, which is resposible for the structure of ice and properties of liquid water (water molecules interacts each other by hydrogen bond), so they are very important forces!

Polarizability is the trend of a molecule to became more polar (when exist a net charge differences in the molecule).

they are made of gases.

they have a spherical shape.

they make energy through fusion.
