Which one of the following is expected to exhibit optical isomerism? (en = ethylenediamine

)

Options

A $c i s-\left[\mathrm{Pt}\left(\mathrm{NH}_3\right)_2 \mathrm{Cl}_2\right]$
Btrans- $\left[\mathrm{Co}(\mathrm{en})_2 \mathrm{Cl}_2\right]$
C $\operatorname{trans}-\left[\mathrm{Pt}\left(\mathrm{NH}_3\right)_2 \mathrm{Cl}_2\right]$
D $\operatorname{cis}-\left[\left(\mathrm{Co}(\mathrm{en})_2 \mathrm{Cl}_2\right]\right.$

Correct answer

B. trans- $\left[\mathrm{Co}(\mathrm{en})_2 \mathrm{Cl}_2\right]$

Step-by-step solution

Cis (-\left[\mathrm{Co}(\mathrm{en})_2 \mathrm{Cl}_2\right]^{+}) is able to show the phenomenon of optical isomerism because it can form a superimposable mirror image. Which one of the following is expected to exhibit optical isomerism? (en = ethylenediamine )

It gives super imposable structure but trans-form is optically inactive. Which one of the following is expected to exhibit optical isomerism? (en = ethylenediamine )
