Chapter 14, Problem 14B.4AE

Interpretation Introduction

Interpretation:

The average interaction energy for pairs of molecules in the gas phase has to be calculated with $\mu =1\text{ D}$ at $298\text{ K}$.  The corresponding answer has to be compared with the average molar kinetic energy of the molecules.

Concept introduction:

The dipole forces are attractive forces between two permanent dipoles.  The interaction is between the positive end of one polar molecule and the negative end of another polar molecule.  The induced dipole interaction occurs when an ion or a dipole induces a temporary dipole in an atom or a molecule with no dipole.  The induced dipole forces are the attraction forces between molecules having temporary dipoles.
