Vedclass · Answer

(B) Enantiomorphs (or enantiomers) are non-superimposable mirror images of each other.For a coordination complex to exhibit optical isomerism (enantiomerism),it must lack a plane of symmetry and a center of inversion.In the complex $[Co(en)_2Cl_2]^+$,the $cis$-isomer lacks a plane of symmetry and thus exists as a pair of enantiomorphs ($d$ and $l$ forms).The $trans$-isomer of $[Co(en)_2Cl_2]^+$ possesses a plane of symmetry and is optically inactive.Other options like $[Cr(NH_3)_6][Co(CN)_6]$,$[Pt(NH_3)_4][PtCl_6]$,and $[Co(NH_3)_4Cl_2]NO_2$ do not exhibit optical isomerism due to the presence of planes of symmetry in their structures.

Which of the following will give a pair of enantiomorphs?
