Complex$\left[\mathrm{C}\mathrm{o}{\left(\mathrm{N}{\mathrm{H}}_3\right)}_4\mathrm{C}{\mathrm{l}}_2\right]\mathrm{C}\mathrm{l}$have two G.I. which are optically inactive due to presence of plane of symmetry.

Complex$\left[\mathrm{C}\mathrm{o}{\left(\mathrm{N}{\mathrm{H}}_3\right)}_3\mathrm{C}{\mathrm{l}}_3\right]$also have two optically inactive geometrical isomers due to presence of plane of symmetry.

Complex$\mathrm{c}\mathrm{i}\mathrm{s}[\mathrm{C}\mathrm{o}\left(\mathrm{e}\mathrm{n}{)}_2\mathrm{C}{\mathrm{l}}_2\right]\mathrm{C}\mathrm{l}$is optically active due to formation of non-superimposable mirror image



$\mathrm{t}\mathrm{r}\mathrm{a}\mathrm{n}\mathrm{s}[\mathrm{C}\mathrm{o}\left(\mathrm{e}\mathrm{n}{)}_2\mathrm{C}{\mathrm{l}}_2\right]\mathrm{C}\mathrm{l}$

Complex$\mathrm{t}\mathrm{r}\mathrm{a}\mathrm{n}\mathrm{s}[\mathrm{C}\mathrm{o}\left(\mathrm{e}\mathrm{n}{)}_2\mathrm{C}{\mathrm{l}}_2\right]\mathrm{C}\mathrm{l}$is optically inactive.
