The complex \(\left[\mathrm{PtCl} \mathrm{C}_{2}(\mathrm{en})_{2}\right]^{2+}\) ion shows
- A structural isomerism only
- B optical isomerism only
- C geometrical and optical isomerism
- D geometrical isomerism only
Answer & Solution
Correct Answer
(C) geometrical and optical isomerism
Step-by-step Solution
Detailed explanation
\(\left[\mathrm{PtCl}_{2}(\mathrm{en})_{2}\right]^{2+}\) complex forms geometrical isomers (cis and trans). Trans-isomer does not show optical isomerism, since it is symmetrical while cis-isomer shows optical isomerism as it is unsymmetrical.
