Unlike the other three gases, ammonia is a polar molecule and can hydrogen-bond, so it will experience stronger intermolecular attraction than the others. The other three are subject only to London dispersion forces. London dispersion forces are created by transient, short-lived redistribution of electrons that makes a molecule act as a weak temporary dipole. The molecule is then able to induce polarity in another molecule, thereby creating an attraction between the two molecules.
In general, London dispersion forces are stronger between larger molecules and weaker between smaller molecules. Helium is the only monoatomic gas in this group and hence the smallest in terms of size and diameter of the four. Select personalised ads. Apply market research to generate audience insights.
