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

Options

Astructural isomerism
Bgeometrical isomerism only
Coptical isomerism only
Dgeometrical and optical isomerism

Correct answer

D. geometrical and optical isomerism

Step-by-step solution

[ PtCl ₂( en )₂ ]²⁺ shows both geometrical and optical isomerism as the complex forms cis and trans isomers. trans-isomer doesn't show optical isomerism since it is symmetrical but cis-isomer shows optical isomerism as it is unsymmetrical.
