Which one of the following coordination entity is chiral?

Options

  1. Atrans - [ CrCl ₂( ox )₂ ]³⁻
  2. Bcis- [ Co ( NH ₃ )₄ Cl ₃ ]⁺
  3. Ccis-[CrCl . C ₂( ox )₂ ]³⁻
  4. Dtrans- [ Co ( NH ₃ )₄ Cl ₂ ]⁺

Correct answer

C. cis-[CrCl . C ₂( ox )₂ ]³⁻

Step-by-step solution

Octahedral complex of general formula [M(A A)₂ a₂ ]^ n show optical isomerism. Trans form of [M(A A)₂ a₂ ]^ n does not show optical isomerism due to symmetry. cis-[Co(NH . .)₃ )₄ Cl ₂ ]⁺ and trans- [ Co ( NH ₃ )₄ Cl ₂ ]⁺ do not show optical isomerism due to symmetry.
