Chapter 11.2, Problem 2PE

Interpretation Introduction

Interpretation: Three species with same structure and same value of $k$ and size of ${\text{Ti}}^{+4}$ is given. The compound among ${\text{TiO}}_{\text{2}}$, ${\text{CaCl}}_{\text{2}}$ and ${\text{PbBr}}_2$ that has the highest melting point is to be stated.

Concept introduction: Stronger is the intermolecular interaction higher will be the melting point.

To determine: The compound among ${\text{TiO}}_{\text{2}}$, ${\text{CaCl}}_{\text{2}}$ and ${\text{PbBr}}_2$ that has the highest melting point.
