Solution

(a) $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_5 \mathrm{NO}_2\right] \mathrm{Cl}_2$ and $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_5 \mathrm{ONO}\right] \mathrm{Cl}_2$ - linkage Isomerism due to difference in binding site. NEET 2022 Chemistry, Coordination Compounds — solution figure 1

(b) $\left[\mathrm{Cr}\left(\mathrm{NH}_3\right)_6\right]\left[\mathrm{Co}(\mathrm{CN})_6\right]$ and $\left[\mathrm{Cr}(\mathrm{CN})_6\right]\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right]$ - It is an example of coordination Isomerism due to exchange of ligands between the two coordination spheres. (c) $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_5\left(\mathrm{SO}_4\right)\right] \mathrm{Br}$ and $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_5 \mathrm{Br} \mathrm{SO}_4\right.$ - It is an example of Ionisation Iosmerism arising due to formation of different ions due to ionisation. The case arises due to exchange of ions between the coordination sphere and ionisation sphere. (d) $\left[\mathrm{Cr}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right] \mathrm{Cl}_3$ and $\left[\mathrm{Cr}\left(\mathrm{H}_2 \mathrm{O}\right)_5 \mathrm{Cl}\right] \mathrm{Cl}_2 \cdot \mathrm{H}_2 \mathrm{O}$ - It is an example of solvate isomerism arising due to difference in $\mathrm{H}_2 \mathrm{O}$ molecules acting as potential ligand and as water of crystallisation.
