Which of the following complex show optical isomerism? (i) cis- [ COCl ( en )₂ ( NH ₃ ) ]²⁺ (ii) cis- [ CrCl ₂( ox )₂ ]³⁻ (iii) cis- [ CO ( en )₂ Cl ₂ ] Cl (iv) cis CO ( NH ₃ )₄ Cl ₂ ]⁺
Options
- A(i), (ii), (iii)
- B(i), (ii)
- C(i), (iv)
- D(i), (ii), (iv)
Correct answer
A. (i), (ii), (iii)
Step-by-step solution
Octahedral complex having general formula [M(A A)₂ a₂ ]^ n or [M(A A)₂ a b ]^ n , shows optical isomersim. cis- [ Co ( NH ₃ )₄ Cl ₂ ]⁺ does not show optical isomerism due to symmetry, while other three complexes show optical isomerism.
