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.
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.
Two noble gases can exhibit this bonding attraction usually when at low temperature. The temporary dipole cause a temporary charge separation and can lead to attraction.
Long hydrocarbons of long chains also exhibits this bonding which can cause a rise in their boiling point.
Ammonia and nitrogen gas will exhibit hydrogen bonding, a strong dipole - dipole attraction.
Hydrogen fluoride and methanol has hydrogen bonds likewise dimethyl either and acetone.
