Chapter 21, Problem 21.51QP

Interpretation Introduction

Interpretation:

The shapes of given ions and why ${\text{AlCl}}_{\text{6}}{}^{\text{3-}}$ does not form has to be described.

Concept introduction:

• Aluminium produce complex ions with reaction of chlorine and fluorine are ${\text{AlCl}}_{\text{4}}{}^{\text{-}}{\text{ and AlF}}_{\text{6}}{}^{\text{3-}}$
• Aluminum ion size is relatively small as compared with chlorine and fluorine
• These complex ions are formed due to unshared electrons present in aluminum with 4 or 6 attached atoms.
