Which of the following coordination compounds would exhibit optical isomerism?

A.Pentamminenitrocobalt (III) iodide

B.Diamminedinitroplatinum (II)

C.trans-dicyanobis (ethylenediamine)

D.Tris-(ethylenediamine) cobalt (III) bromide✓ Correct

Explanation

Here, for a complex to show optical isomerism, plane of symmetry should be absent. As plane of symmetry is absent in the complex- Tris (ethylenediamine) cobalt (III) bromide therefore it shows the following optical isomers. Therefore, option (d) is the correct answer.
