The complex cation which has two isomers is:

Options

  1. ACo H 2 O 6 3 +
  2. BCo NH 3 5 Cl 2 +
  3. CCo NH 3 5 NO 2 2 +
  4. DCo NH 3 5 Cl +

Correct answer

C. Co NH 3 5 NO 2 2 +

Step-by-step solution

The complex shows linkage isomerism in the presence of ambidentate ligands. Co NH 3 5 NO 2 2 + shows linkage isomerism, because NO 2 - ligand is ambidentate ligand.
