The complex [ PtCl C ₂( en )₂ ]²⁺ ion shows

Options

Astructural isomerism only
Boptical isomerism only
Cgeometrical and optical isomerism
Dgeometrical isomerism only

Correct answer

C. geometrical and optical isomerism

Step-by-step solution

[ PtCl ₂( en )₂ ]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.
