Chapter 11, Problem 104RQ

Using the information in Problem 11.102, list the compounds in order from highest vapor pressure to lowest vapor pressure at $\text{25 °C}$.

The boiling points of some common substances are as follows:

Ethanol, ${\text{C}}_{\text{2}}{\text{H}}_{\text{5}}\text{OH}$	$\text{78}\text{.4 °C}$
Ethylene glycol, ${\text{C}}_{\text{2}}{\text{H}}_{\text{4}}{\left(\text{OH}\right)}_{\text{2}}$	$\text{197}\text{.2°C}$
Water	$\text{100°C}$
Diethyl ether, ${\text{C}}_{\text{4}}{\text{H}}_{\text{10}}\text{O}$	$\text{34}\text{.5 °C}$

Arrange these substances in order of increasing strengths of intermolecular attractions.
