The intermolecular attractive forces that exist even in non-polar gases like hydrogen, oxygen and nitrogen help in liquefying gases.
In polar gases like NH3, dipole-dipole attractions exist due to difference in electronegativity between the atoms.
In non-polar gases having homonuclear diatomic molecules (like H2, O2 etc), induced dipole-dipole interactions takes place, as the electron pair forming the covalent bond is not always equally shared by the two atoms.
