Chapter 10, Problem 72QP

Interpretation Introduction

Interpretation:

An explanation for the difference between the melting points of ${\text{CF}}_4$ and ${\text{CCl}}_{\text{4}}$ is to be written.

Concept Introduction:

The melting point of a solid depends on its intermolecular forces. The stronger the intermolecular forces, the higher will be the melting point of the solid.

The intermolecular forces of different non-polar substances only depend on the strength of the London dispersion forces.

London dispersion forces increase with an increase in the size of the molecules because of the large electron cloud that can be distorted easily to form a temporary dipole.
