Question

The two compounds pantammine sulphato cobalt $\left(III\right)$ bromide and pantaammine sulphato cobalt $\left(III\right)$ chloride represent:

• A. Linkage isomerism
• B. Ionization isomerism
• C. Co-ordination isomerism
• D. No isomerism

Answer 1

Answer: (D)

No isomerism

$\left[Co\right(N{H}_3{)}_{5}S{O}_4]Br$ $\left[Co\right(N{H}_3{)}_{5}S{O}_4]Cl$

Linkage isomerism is the isomerism occurs due to the difference in the connectivity of the ligand to metal.

Linkage isomerism is possible with ambidentate ligands only.

In ionisation isomerism, exchange of ligands occur from secondary valency to primary valency.

In coordination isomerism, swapping the species from the inner coordination sphere to one metal to inner coordination sphere of a different metal in the compound.

The given compounds are not showing any isomerism. Hence, the answer is option D.
