Chapter 19, Problem 86E

Interpretation Introduction

(a)

Interpretation:

Among ${\text{CH}}_{\text{3}}\text{COOH}$ or ${\text{HCOOCH}}_3$, the compound that has the higher boiling point is to be stated.

Concept introduction:

The vapor pressure is defined as the pressure exerted by the vapor of the substances that are in equilibrium with the condensed phase at a given temperature. The temperature at which the atmospheric pressure is equal to the vapor pressure is known as the boiling point.
