Chapter 19, Problem 85E

Interpretation Introduction

(a)

Interpretation:

Among ${\text{CH}}_{\text{3}}{\text{OCH}}_{\text{3}}$ or ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}\text{OH}$, 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.

Interpretation Introduction

(b)

Interpretation:

Among ${\text{CH}}_{\text{3}}{\text{CH}}_2{\text{CH}}_2{\text{NH}}_2$ or ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}\text{F}$, the compound that has the higher boiling point is to be stated.
