Chapter 14, Problem 9STP

Interpretation Introduction

Interpretation:

The intermolecular forces exhibited by ${\text{O}}_{\text{2}}$ (Oxygen) molecule is to be explained.

Concept introduction:

Oxygen is a gas and it’s a diatomic molecule.

Answer to Problem 9STP

London Dispersion forces are the intermolecular force exists in oxygen molecule.

Explanation of Solution

The only force existing is the London Dispersion force, as other forces like Hydrogen bonding & Dipole-dipole / ion-dipole forces do not occur because of the absence of Hydrogen atom and for dipole -dipole / ion-dipole forces a dipole in the molecule must be present. For oxygen molecule, it doesn’t form a dipole because it has zero dipole moment as its electron pair is equally shared between the two oxygen atoms in a molecule.
