Question
In which of the following pairs both the complexes do not show optical isomerism ?
Options
A.cis- [Cr(en)2Cl2] and cis - [Co(NH3)4Cl2]
B.[Co(gly)3] and cis-[CoCl2(en)2]
C.[Pt (en)Cl2] and fac- [Ni(NH3)3Cl3]
D.mer - [Co(NO3)3(NH3)3] and [PtCl2(en)]
Solution
(A) cis-[Co(NH3)4Cl2] does not show optical isomerism due to the presence of symmetry element.
(C) For same reason [Ni(NH3)3Cl3] and [Pt(en)Cl2].
(C) For same reason [Ni(NH3)3Cl3] and [Pt(en)Cl2].
