Which of the following complex species is not expected to show optical isomerism ?

A

`[Co(en)(NH_3)_2Cl_2]^(+)`

B

`[Co(en)_3]^(3+)`

C

`[Co(en)_2Cl_2]^(+)`

D

`[Co(NH_3)_3Cl_3]`

Text Solution

Verified by Experts

The correct Answer is:
D
`[Co(NH_3)_3Cl_3]` shows cis or facial (fac) as well as trans or meridional (mer) isomers. But both these isomers contain plane of symmetry. So they do not exhibit opitcal isomerism.
