Name the type (s) of intermolecular forces that exists between molecules (or basic units) in each of the following species. (Select all that apply.) (a) CH4 dipole-dipole dispersion ion-dipole ion-ion (b) NO2 dipole-dipole dispersion ion-dipole ion-ion (c) SOZ dipole-dipole dispersion ion-dipole O ion-ion

(a) CH₄

The molecule of methane is non polar in nature, hence it will show only the dispersion forces.

(b) NO₂

The molecule of nitrogen dioxide will show both dipole-dipole interactions and dispersion forces as well.

Since, the molecule is has an electronegative atom, i. e., oxygen, so will show dipole - dipole interactions.

(c) SO₂

The molecule of sulfur dioxide will show both dipole-dipole interactions and dispersion forces as well.

Since, the molecule is has an electronegative atom, i. e., oxygen, so will show dipole - dipole interactions.
