1.	Co-ordiantion compounds show structural isomerism and it is different from the nature of the isomerism which we generally come across in organic compounds. The co-ordination and linkage isomers depending upon their upon the number of ions which they furnish upon dissociation in aqueous solution . The isomers belonging to a particular type can also be distinguished from each structural isomerism, the co-ordination compounds are also involved in geometrical and optical isomerism. Whereas optical octahedral and square planar complexes can exhibit geometrical isomerism. Which of the following will not show geometrical isomerism ?A. `[Cr(NH_(3))_(4)Cl_(2)]Cl`B. `[CoCl_(2)(en)_(2)]Cl`C. `[Co(NH_(3))_(5)NO_(2)]Cl_(2)`D. `[Pt(NH_(3))_(2).Cl_(2)]`
Answer» Correct Answer - c Octahedral complexes of the type `MA_(5)B` do not show any geometrical isomerism.
