$Cis-[Co(NH_3)_2(en)_2]^{3+}$

Vedclass · Answer

(C) Optical activity in coordination complexes requires the absence of a plane of symmetry and a center of inversion (i.e.,the complex must be chiral).$Trans-[Co(NH_3)_4Cl_2]^+$ has a plane of symmetry and is achiral.$[Cr(H_2O)_6]^{3+}$ is an octahedral complex with identical ligands,possessing multiple planes of symmetry,and is achiral.$Trans-[Co(NH_3)_2(en)_2]^{3+}$ has a plane of symmetry passing through the $Co$ atom and the two $NH_3$ ligands,making it achiral.$Cis-[Co(NH_3)_2(en)_2]^{3+}$ lacks both a plane of symmetry and a center of inversion,making it a chiral molecule that exhibits optical activity.
