Vedclass · Answer

(D) Optical isomerism is exhibited by coordination compounds that lack a plane of symmetry and a center of symmetry.$A$. $[Co(NH_3)_5(NO_2)]I_2$ has a plane of symmetry and is achiral.$B$. $[Pt(NH_3)_2Cl_2]$ is a square planar complex,which is inherently achiral.$C$. The $trans$ isomer of $[Cr(en)_2(CN)_2]^+$ has a plane of symmetry and is achiral.$D$. $[Co(en)_3]Br_3$ contains three bidentate ethylenediamine $(en)$ ligands. This complex does not have a plane of symmetry or a center of symmetry,making it chiral and optically active. It exists as a pair of non-superimposable mirror images (enantiomers).

Which of the following coordination compounds would exhibit optical isomerism?
