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

A)                 \[cis-[Pt{{(N{{H}_{3}})}_{2}}C{{l}_{2}}]\]

B)                 \[trans-[Co{{(en)}_{2}}C{{l}_{2}}]\]

C)                 trans-\[[Pt{{(N{{H}_{3}})}_{2}}C{{l}_{2}}]\]

D)                 \[cis-[Co{{(en)}_{2}}C{{l}_{2}}]\]

Correct Answer: B

Solution :

                Trans \[[Co{{(en)}_{2}}C{{l}_{2}}]\] is able to exhibit the phenomena of optical isomerism because it can form a superimposable mirror image.
