Which of the following does not show optical isomerism - (en = Ethylenediamine)
Options
- A[ Co ( en )₃ ]³⁺
- B[ Co ( en )₂ Cl ₂ ]⁺
- C[ Co ( NH ₃ )₃ Cl ₃ ]⁻
- D[ Co ( en ) Cl ₂ ( NH ₃ )₂ ]⁺
Correct answer
C. [ Co ( NH ₃ )₃ Cl ₃ ]⁻
Step-by-step solution
As complexes of the type [ MA ₃ ~B ₃ ] can show geometrical isomerism knows as facmer isomerism and not optical isomerism. So here [ Co ( NH ₃ )₃ Cl ₃ ]^0 can not show optical isomerism.
