Chapter 19, Problem 50E

Interpretation Introduction

Interpretation: The reason for the compounds of copper(II) being colored and copper(I) are not colored needs to be explained. Also, whether ${\text{Cd(NH}}_{\text{3}}{\text{)}}_{\text{4}}{\text{Cl}}_{\text{2}}$ is colored or not needs to be determined.

Concept introduction: Transition metals generally have partially filled $\text{d or f}$ orbitals. The splitting of d-orbitals due to interaction of ligands with metal and transfer of electrons between these split d-orbitals results in colored metal.
