B

Linkage isomerism, ionization isomerism and geometrical isomerism.

C

Ionisation isomerism, geometrical isomerism and optical isomerism.

D

Ionisation isomerism, geometrical isomerism and optical isomerism.

Step-by-Step Solution

The given complex is [Co(NH3)4(NO2)2]Cl[\text{Co}(\text{NH}_3)_4(\text{NO}_2)_2]\text{Cl}.

  1. It contains the ambidentate ligand NO2−\text{NO}_2^-, which can coordinate through either the nitrogen atom or the oxygen atom. Therefore, it shows linkage isomerism.
  2. The counter ion Cl−\text{Cl}^- can exchange with the ligand NO2−\text{NO}_2^- to form [Co(NH3)4(NO2)Cl]NO2[\text{Co}(\text{NH}_3)_4(\text{NO}_2)\text{Cl}]\text{NO}_2. Thus, it exhibits ionisation isomerism.
  3. It is an octahedral complex of the type [Ma4b2][Ma_4b_2], which exists in two geometrical isomeric forms: cis and trans.
  4. It does not exhibit optical isomerism because both its cis and trans forms possess a plane of symmetry and are optically inactive.
