Choose the coordination compound which does not exhibit Optical activity.
- A \(\left[\mathrm{Co}(\mathrm{en})_3\right]^{3+}\)
- B cis \(-\left[\mathrm{CoCl}_2(\mathrm{en})_2\right]^{+}\)
- C cis \(-\left[\mathrm{PtCl}_2(\mathrm{en})_2\right]^{2+}\)
- D trans \(-\left[\mathrm{CoCl}_2(\mathrm{en})_2\right]^{+}\)
Answer & Solution
Correct Answer
(D) trans \(-\left[\mathrm{CoCl}_2(\mathrm{en})_2\right]^{+}\)
Step-by-step Solution
Detailed explanation
Optical activity in coordination compounds requires the absence of a plane of symmetry and a center of inversion. The complex \(\left[\mathrm{Co}(\mathrm{en})_3\right]^{3+}\) is a tris-chelated octahedral complex which lacks both a plane of symmetry and a center of inversion,…
