Chapter 19, Problem 37E

Interpretation Introduction

Interpretation : The cis isomer of $\text{Co}{\left(\text{en}\right)}_{\text{2}}{\text{Cl}}_2{}^{+}$ is optically active and trans isomer is not optically active. Whether the same is true for $\text{Co}{\left({\text{NH}}_{\text{3}}\right)}_{\text{4}}{\text{Cl}}_2{}^{+}$ complex or not needs to be determined.

Concept Introduction : In a coordinate complex, neutral molecule or ion also known as ligands which are electron deficient and form bonds with metal ion which are electron efficient. Generally, metal that belongs to d-block form coordinate complexes.
