Which of the following statement is false?

Options

A. Optical isomerism is observed in `[M(abcd)]^(n+-)` tetrahedral complexes.
B. Geometrical isomerism does not eists while optical isomerism exists in the complex `[Fe(C_(2)O_(4))_(3)]^(3-)`
C. Both cis and trans are optically inactive in `[PtCl_(2)(NH_(3))_(4)]^(2+)` complex ion.
D. `[Pt(en)_(2)]^(2+)` shown geometrical isomerism as well as optical.

Answer

D

Explanation

`[M(AA)_(2)]^(n+-)` does not show geometrical isomerism and can not show optical
