Which of the followingg statement(s) is/are false?

Answer»

In `[PtCl_(2)(NH_(3))_(4)]^(2+)` complex ion, the cis-form is optically active, while trans-form is optically inactive
In `[Fe(C_(20O_(4))_(3)]^(3-)`, GEOMETRICAL isomerism does not exist, while optical isomerism exist
In `[Mabcd]^(N+-)` tetrahedral complexes, optical isomerism cannot be observed
In `[Mabcd]^(n+-)` square planar complex, optical isomerism can be observed

Solution :`[PtCl_(2)(NH_(3))_(4)]^(2+)implies` both cis and trans forms are optically inacctive
(b)
`implies`Due to asymmetrical configuration, it exhibits optical isomerism.
(c)
`implies`Due to PLANE of symmetry does not EXHIBIT optical isomerism, but exhibits geometrical isomerism.
(d)
`implies`Tetrahedral complex, asymmetric configuration, hence exhibits optical isomerism.
