Ashortcut to finding optical isomers is to see if the complex has a plane of symmetrya plane passing through the metal atom such that every atom on one side of the plane is matched by an identical one at the same distance from the plane on the other side. Any planar complex has a plane of symmetry, since all atoms lie in one plane. Use this approach to determine whether these exist as optical isomers: (a) [Zn(NH3)2Cl2] (tetrahedral); (b) [Pt(en)2]2_; (c) trans-[PtBr4Cl2]2_; (d) trans-[Co(en)2F2]_; (e) cis-[Co(en)2F2]_.
