[Co(NH3)4Cl2]NO2 and [Co(NH3)4ClNO2]Cl exhibit whcih type of isomerism?

  • Geometrical

  • Optical

  • Linkage

  • Ionisation


D.

Ionisation

[Co(NH3)4Cl2]NO2 and [Co(NH3)4ClNO2]Cl give diiferent ions on ionisation as

[Co(NH3)4Cl2]NO2 [Co(NH3)4Cl2] + NO2-[Co(NH3)4ClNO2]Cl[Co(NH3)4ClNO2]+ + Cl-

Thus, they show ionisation isomerism.
