Chapter 12, Problem 31E

Interpretation Introduction

Interpretation:

The compound that is most volatile is to be determined.

Concept Introduction:

The boiling point of a molecule depends upon the intermolecular forces and thermal energy.

Intermolecular forces are of two types: Dispersion forces and dipole forces.

Dispersion forces are possessed by all atoms and molecules and depend upon the molar mass.

Dipole forces exist between polar molecules and depend upon the polarity of molecules.

Boling point also increases when there is intermolecular hydrogen bonding.

Molecules which have low boiling points vaporize easily and are called volatile liquids.
