Question
Select the correct statement (s)
Options
A.[Co(EDTA)]- has two optical isomers
B.[Co(NH3)5(NO2)]2+ show linkage isomerism.
C.For [Pt (NH3)BrClI(NO2)py ], theoretically fifteen different geometrical isomers are possible.
D.[Cr(H2O)4Cl2]Cl2.2H2O is an example of hydrate as well as ionisation isomerism.
Solution
(A) [Co(EDTA)]- shows optical isomerism.
(B) NO2- being bidentate ligands can attach to central metal ion through N or O.
(C) It is Mabcdef type and thus have fifteen different geometrical isomers.
(D) Ionisation isomerism involves exchange of different ions between coordination sphere and ionisation sphere. In complex, [Cr(H2O)4Cl2]Cl2.2H2O, same anionic ligands, i.e., Cl- are present in coordination sphere and ionisation sphere; so no exchange of ions takes place.
