Which of the following does not have optical isomer?

A

`[Co(NH_(3))_(3)Cl_(3)]`

B

`[Co(En)_(2)Cl_(3)]`

C

`[Co(en)_(2)Cl_(2)]Cl`

D

`[CO(en)(NH_(3))_(2)Cl_(2)]Cl.`

Text Solution

Verified by Experts

The correct Answer is:
A
Coordination compounds which must have centre of symmetry are optically unactive . In CN = 6 due to presence of chelating ring it most make it non-superimposable on narrow image so that except `[Co(NH_(3))_(3)Cl_(3)]` others are optically active.
