Chapter 8, Problem 29E

(a)

Interpretation Introduction

To determine: The experiment to confirm the formation of $\left[{\text{CoCl}}_2{\left(\text{en}\right)}_2\right]\text{Cl}$ in the given reaction.

(b)

Interpretation Introduction

To determine: If the cobalt present in the given reaction is in $+3$ oxidation state or not; also the spin state of cobalt in the given complex.

(c)

Interpretation Introduction

To determine: The existence of geometrical isomerism in the complex $\left[{\text{CoCl}}_2{\left(\text{en}\right)}_2\right]\text{Cl}$ ; also the way to distinguish them in the reaction product.

(d)

Interpretation Introduction

To determine: The way to know the isomer which is formed as a product in the given reaction out of the two isomers.
