• a. [CoF6]3-

• [Co(CNS)4]2-

• [Mn(H2O)6]2+

• [Co(NH3)6]3+

• Linkage Isomerism

• Ligand Isomerism

• Coordination Isomersim

• Optical Isomerism

• Both the complexes give yellow colour precipitate

• Both the complexes give white colour precipitate

• Complex A gives yellow precipitate and Complex B gives white precipitate

• Complex A gives white precipitate and Complex B gives yellow precipitate

In this type of isomerism, the emprical formula of the complexes will be the same; but the isomeric complexes will have different molecular formulae

• Coordination Isomerism

• Ligand Isomerism

• Polymerization Isomerism

• True

• False

• True

• False
