Select the correct statements regarding `[Pt(en)(pn)Cl_(2)]^(2+)` ion.

Options

A. It exhibits optical isomerism
B. It exhibits geometrical isomerism.
C. All isomers are optically active
D. It is diamagnetic in nature

Answer

A, B, C, D

Explanation

`[Pt(en)(pn)Cl_(2)]^(2+) : Pt^(4+) : 5d^(6) : d^(2)sp^(3)` (unpaired electrons are zero)

and both geometrical isomers are optically active.
