Chapter 8, Problem 8.111QP

Interpretation Introduction

Interpretation: The more likely existence of dimethylaluminium chloride as ${\left({\text{CH}}_{\text{3}}\right)}_{\text{4}}{\text{AlCl}}_{\text{2}}$ than as ${\left({\text{CH}}_{\text{3}}\right)}_2\text{AlCl}$ is to be explained by using Lewis structure.

Concept introduction: The Lewis structures are diagrams that give information about the bonding electron pairs and the lone pairs of electrons in a molecule. Similar to electron dot structure in Lewis diagram the lone pair electrons are represented as dots and they also contain lines which represent bonding electron pairs in a bond.

To determine: An explanation for the more likely existence of dimethylaluminium chloride as ${\left({\text{CH}}_{\text{3}}\right)}_{\text{4}}{\text{AlCl}}_{\text{2}}$ than as ${\left({\text{CH}}_{\text{3}}\right)}_2\text{AlCl}$ by using Lewis structure.
