Optical isomerism is exhibited by (ox = oxalate anion, en = ethylenediamine)-

A

`cis - [CrCl_(2)(o x)_(2)]^(3-)`

B

`[Co(en)_(3)]^(3+)`

C

`trans - [CrCl_(2)(o x)_(2)]^(3-)`

D

`[Co(ox)(en)_(2)]^(+)`

Text Solution

Verified by Experts

The correct Answer is:
A, B, D
trans-`[CrCl_(2)(o x)_(2)]^(3-)` does not show optical isomerism as it contains plane of symmetry. There is no element of symmetry present in outer three compounds. Hence they show optical isomerism.
