Which of the following can be best explained by temporary dipole moments?

Choose one or more:
A. This explains why ammonia and nitrogen gas exhibit an attractive force between them.
B. This explains how two noble gases' molecules can have an attractive force between them.
C. This explains why long hydrocarbon chains have relatively high boiling points.
D. This explains how the molecules hydrogen fluoride and methanol can exhibit uncharacteristically strong intermolecular forces.
E. This explains why the dipole-dipole attractive force between dimethyl ether and acetone does not entirely account for the attractive force between these molecules.

Temporary dipole moments explains how two noble gases' molecules can have an attractive force between them.

Dispersion forces are known to arise as a result of temporary dipoles which arise in molecules and cause dipoles to become induced in other neutral molecules. Dipole - induced dipole interactions are common in nonpolar substances.

Hence, temporary dipole moments explains how two noble gases' molecules can have an attractive force between them. Also, this explains why long hydrocarbon chains have relatively high boiling points.

Explanation:

Temporary dipole moments are weak intermolecular force of attraction between two or more compounds. They are the weakest of intermolecular forces. They form when non-polar molecules becomes polar due to the constant motion of their electrons. This may lead to an uneven charge distribution at an instant.

When this occurs, the molecule has a  temporary dipole. The dipole can induce neighboring molecules to be distorted and form dipoles as well.
