Chapter 21, Problem 21.57QP

Interpretation Introduction

Interpretation:

The change in bonding when ${\text{Al}}_{\text{2}}{\text{Cl}}_{\text{6}}$ dissociates to form ${\text{AlCl}}_{\text{3}}$ in the gas phase has to be explained.

Concept introduction:

• With the help of hybridization we can easily know the bond change in molecules.
• First of all, know the number of bonding pair electrons in ${\text{Al}}_{\text{2}}{\text{Cl}}_{\text{6}}$ from its structure and detemine the hybridization of ${\text{Al}}_{\text{2}}{\text{Cl}}_{\text{6}}$
• Then finally come to dissociated ${\text{AlCl}}_{\text{3}}$ with its geometry determine the hybridization.
• Clearly we can say that bond changes in a molecule with the help of its hybridization change.
