(a)
Interpretation:
The name that would be ascribed to the strongest interaction that exists between
Concept introduction:
The dominant intermolecular interaction between non-polar molecules is called induced dipole-induced dipole interactions or London dispersion forces. In a molecule, electrons are constantly moving around and at some instant in time, there may be more electrons on one side of the molecule than there are on the other. The extra electrons on that one side gives rise to instantaneous dipole which can alter the electron distribution on a second molecule by repelling or attracting nearby electrons. This instantaneous dipole is directly proportional to the number of electrons possessed by the molecule that is on the molar mass. Ionic compounds have the strongest type of interaction – ion-dipole interactions.
(b)
Interpretation:
Among the pairs, which pair of species would be expected to have a stronger attractive interactions, is to be identified.

Greater the number of electrons, greater will be the strength of induced-dipole interactions.
