Vedclass · Answer

(C) Optical isomerism is exhibited by complexes that lack a plane of symmetry and a center of symmetry (chiral complexes).For octahedral complexes of the type $[M(AA)_3]$,where $AA$ is a bidentate ligand like ethylenediamine $(en)$,the complex exists as a pair of enantiomers (non-superimposable mirror images).In the given options,$[Co(en)_3]Cl_3$ contains three bidentate ligands,which creates a chiral environment around the central metal ion,thus exhibiting optical isomerism.The other complexes listed are either of the type $[MA_5B]$ or $[MA_4BC]$,which generally exhibit geometrical isomerism but not optical isomerism.
