Chapter 9.7, Problem 9.8.1PE

Interpretation Introduction

Interpretation: The formulation of the two complexes is given. Also, the reactivity of the complexes with ${\text{AgNO}}_{\text{3}}\left(aq\right)$ and ${\text{BaCl}}_{\text{2}}$ is given. Various questions based on the given information are to be answered.

Concept introduction: The oxidation number of central metal in the complex depends on both primary valency and secondary valency of the complex.

The reactivity of the complex is depending upon the ionisable ions that are present out of the coordination sphere.

In Coordination isomerism, molecular formula of the complex is same. there is interchange between the electron donating group inside and outside the coordination sphere of the complex.

(a)

To determine: The oxidation state of $\text{Co}$ in $\left[\text{Co}\left(\text{Br}\right){\left({\text{NH}}_{\text{3}}\right)}_{\text{5}}\right]{\text{SO}}_{\text{4}}$ and $\left[\text{Co}\left({\text{SO}}_{\text{4}}\right){\left({\text{NH}}_{\text{3}}\right)}_{\text{5}}\right]\text{Br}$ .

(b)

Interpretation Introduction

To determine: The explanation for the reactivity of compound A and compound B with ${\text{AgNO}}_{\text{3}}\left(aq\right)$ and ${\text{BaCl}}_{\text{2}}$ .

(c)

Interpretation Introduction

To determine: The type of isomerism observed in the given complexes.

(d)

Interpretation Introduction
