Chapter 16, Problem 21E

Interpretation Introduction

Interpretation: The compound that has a boiling point nearest to argon needs to be determined from ${\text{Cl}}_{\text{2}}{\text{, HCl, F}}_{\text{2}}\text{, NaF}$ and $\text{HF}$ .

Concept Introduction: The temperature at which the pressure surrounding the liquid and the vapor pressure of the liquid becomes equal is said to be its boiling point. At this temperature, the phase changes from liquid to vapor.

The strength of intermolecular forces present between the molecules influences the properties of the substance like boiling point, vapor pressure, etc. If the strength of the intermolecular forces is strong then it results in higher boiling point and low vapor pressure of the liquid.
