Chapter 11, Problem 56E

Interpretation Introduction

(a)

Interpretation:

Among ${\text{H}}_{\text{2}}\text{O}$ and ${\text{H}}_{\text{2}}\text{Se}$, the compound having higher boiling point is to be stated.

Concept introduction:

The boiling point is the temperature at which the vapor pressure of the liquid becomes equal to the atmospheric pressure. The boiling point of a compound is directly proportional to its intermolecular forces of attractions and the molar mass of the compound.
