Chapter 10, Problem 71QP

Interpretation Introduction

Interpretation:

The explanation for the difference in the boiling points for $\text{He}$ and ${\text{H}}_2$ is to be written.

Concept Introduction:

The boiling point of a substance depends on the strength of the intermolecular forces present in the substance. An increase in the strength of the intermolecular forces increases the boiling point of substances. Nonpolar molecules have only London dispersion force whereas polar molecules might have both dipole-dipole force and hydrogen bonding force.
