Question
Which of the following isomerisms is/are shown by the complex [CoCl2(OH2)2(NH3)2 ]Br ?
Options
A.Ionization
B.Linkage
C.Geometrical
D.optical
Solution
(A) [CoCl2(OH2)2(NH3)2]Br and [CoClBr(OH2)2(NH3)2]Cl are ionisation isomers.
(B) Does not have ambidentate ligand; so does not show linkage isomerism.
(C) It is Ma2b2c2 type.
Ma2b2c2 - 5 (aa)(bb)(cc) (optically inactive)
(aa)(bc)(bc) (optically inactive)
(bb)(ac)(ac) (optically inactive)
(cc)(ab)(ab) (optically inactive)
(ab)(ac)(bc) (optically active)
