What type of intermolecular force occurs between all substances?

Covalent bonding

Hydrogen bonding

Ion-dipole force

London dispersion force

Between london dispersion force because this occurs between non polar molecules and as well as all molecules.

London dispersion force

Explanation:

Covalent bonding is present between atoms and it is not present as intermolecular forces, generally.

Hydrogen bond is present in the molecule where hydrogen atom is bonded to a highly electro-negative element (F, O or N) and another highly electro negative element (F, O or N).

Ion dipole force is present between an ion and a dipole.

So for these forces, there should have permanent polarity in the molecule.

London dispersion forces are due to temporary attractive force due to formation of temporary dipoles created by the asymmetry in position of electrons in an atom. This condition may occur in all kind of molecule, polar or non polar.
