(a)

Interpretation Introduction

Interpretation:

The type of isomer represented by the pair $\left[\text{Cu}{\left({\text{NH}}_{\text{3}}\right)}_{\text{4}}\right]\left[\text{Pt}\left({\text{Cl}}_{\text{4}}\right)\right]$ and $\left[\text{Pt}{\left({\text{NH}}_{\text{3}}\right)}_{\text{4}}\right]\left[\text{Cu}\left({\text{Cl}}_{\text{4}}\right)\right]$ has to be given.

Concept Introduction:

Isomers:

The compounds with same molecular formula but differ in the arrangement of the atom are said to be isomers.

Coordination Isomers:

Coordination isomerism arises in compounds containing complex anionic and cationic parts.  Hence, there are two complex compounds bound together, one with a negative charge and the other with a positive charge.  In coordination isomers, the anion and cation complexes of a coordination compound exchange one or more ligands.

(b)

Interpretation Introduction

Interpretation:

The type of isomer represented by the pair $\left[\text{Cr}{\left({\text{NH}}_{\text{3}}\right)}_{\text{4}}{\left(\text{OH}\right)}_{\text{2}}\right]\text{Br}\text{\&}\left[\text{Cr}\text{Br}{\left({\text{NH}}_{\text{3}}\right)}_{\text{4}}\left(\text{OH}\right)\right]\left(\text{OH}\right)$ has to be given

Concept Introduction:

Ionization Isomers:

Ionization isomers occur when a ligand is bound to the metal center exchanges places with an anion or neutral molecule that was previously outside the coordination complex.
