Repulsion of electrons within two interacting molecules produces changes in elec

Question

Repulsion of electrons within two interacting molecules produces changes in electron distribution. This change in electron distribution creates temporary dipole moments. Which of the following does this explain? Select all that apply. This explains why long hydrocarbon chains have relatively high boiling points. This explains how two noble gases' molecules can have an attractive force between them. This explains why the dipole-dipole attractive force between dimethyl ether and acetone does not entirely account for the attractive force between these molecules. This explains why ammonia and nitrogen gas exhibit an attractive force between them. This explains how the molecules hydrogen fluoride and methanol can exhibit LJ uncharacteristically strong intermolecular forces.

Explanation / Answer

This type of attraction is called induced dipole-induced dipole forces or weak vanderwall forces or London force or dispersion forces. It occur between two non polar molecule.

Similar force exist between polar and non polar called dipole-induced dipole forces.

It explain following:-

A. long hydrocarbon have high boiling point.

B. Attraction between noble gases

C. Secondary forces between acetone and dimethyl ether.

D. Force between NH3 and N2
