Vedclass · Answer

(B) Optical isomerism is exhibited by complexes that lack a plane of symmetry and are non-superimposable on their mirror images.In the complex $[Co(en)_2Cl_2]^+$,the cis-isomer does not have a plane of symmetry and thus exists as two enantiomeric forms (d and l).The trans-isomer of $[Co(en)_2Cl_2]^+$ has a plane of symmetry and is optically inactive.Other options like $[Cr(NH_3)_2Cl_2]^+$,$[Co(NH_3)_4Cl_2]^+$,and $[Zn(en)_2]^{2+}$ possess planes of symmetry in their stable configurations,making them optically inactive.

Which of the following complex ions will exhibit optical isomerism? ($en = 1, 2$-diamine ethane).
