Options

A(a)-(iii), (b)-(i), (c)-(ii), (d)-(iv)
B(a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)
C(a)-(iii), (b)-(ii), (c)-(i), (d)-(iv)
D(a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)

Correct answer

C. (a)-(iii), (b)-(ii), (c)-(i), (d)-(iv)

Step-by-step 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. <img src="https://cdn-question-pool.Quantrex.app/pyq/neet/XzbJ8M7GLwYWBOAeJQCH18d1Yh3ZKV_hkWQ6cq3cstQ.original.fullsize.png"><br><img src="https://cdn-question-pool.Quantrex.app/pyq/neet/gySwTO-Ds4Iu1wUsxo-xzQ6Ugf4LYS8tRPl4w2LF5hg.original.fullsize.png"><br> (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.
