Vedclass · Answer

(C) Optical isomerism is exhibited by only those complexes which lack elements of symmetry (plane of symmetry or center of symmetry).
$[Co(en)_3]^{3+}$ is a chiral complex and exhibits optical isomerism.
$[Co(en)_2Cl_2]^{+}$ exists in $cis$ and $trans$ forms; the $cis$ form is optically active.
$[Co(NH_3)_3Cl_3]$ exists in facial $(fac)$ and meridional $(mer)$ isomeric forms. Both these forms possess a plane of symmetry,hence they are optically inactive.
$[Co(en)(NH_3)_2Cl_2]^{+}$ can exist in optically active forms depending on the arrangement of ligands.
Therefore,$[Co(NH_3)_3Cl_3]$ is the complex that does not exhibit optical isomerism.
