The complex which does not show optical isomerism is
- A cis \(-\left[\mathrm{Co}(\mathrm{en})_2 \mathrm{Cl}_2\right] \mathrm{Cl}\)
- B cis \(-\left[\mathrm{CiCl}_2(\mathrm{ox})_2\right]^{3-}\)
- C cis \(-\left[\mathrm{CoCl}(\mathrm{en})_2\left(\mathrm{NH}_3\right)\right]^{2+}\)
- D cis - \(\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right]^{+}\)
Answer & Solution
Correct Answer
(D) cis - \(\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right]^{+}\)
Step-by-step Solution
Detailed explanation
Optical isomerism in coordination complexes requires the absence of a plane of symmetry or a center of inversion. Option (1): cis-\([Co(en)_2Cl_2]^{+}\) has no plane of symmetry and is optically active. Option (2): cis-\([CrCl_2(ox)_2]^{3-}\) has no plane of symmetry and is…
