Q.78 How the isomeric complexes [Co(NH3)6][Cr(NO2)6] and [Cr(NH3)6][Co(NO2)6] can be distinguishedfrom one another by(A) conductivity measurement (B) measuring magnetic moments
(C) electrolysis of their aqueous solutions (D) optical measurement
Thse are the examples of coordination isomers. Coordination isomerism is shown by those complex compounds which are composed of complex cation and complex anion. Coordination isomers are obtained when some or all ligands of both the coordination spheres are interchanged with each other. Due to interchange of ligands their conductivty in solution is different.
Hence correct option is A.
Hence correct option is A.
