The complexes [ Co ( NH ₃ )₆ ] [ Cr ( CN )₆ ] and [ Cr ( NH ₃ )₆ ] [ Co ( CN )₆ ] are the examples of which type of isomerism?
Options
- AIonisation isomerism
- BCoordination isomerism
- CGeometrical isomerism
- DLinkage isomerism
Correct answer
B. Coordination isomerism
Step-by-step solution
The complexes [ Co ( NH ₃ )₆ ] [ Cr ( CN )₆ ] and [ Cr ( NH ₃ )₆ ] [ Co ( CN )₆ ] are the examples of coordination isomerisms. This isomerism occurs only in those complexes in which both cation and anion are complex. It occurs due to exchange of ligands between cation and anion.
