JEE MAIN - Chemistry (2015 (Offline) - No. 12)
The number of geometric isomers that can exist for square planar [Pt (Cl) (py) (NH3) (NH2OH)]+ is (py = pyridine) :
3
4
6
2
Explicaţie
Square planar complexes of type $$M\left[ {ABCD} \right]\,$$ form three isomers. Their position may be obtained by fixing the position of one ligand and placing at the trans position any one of the remaining three ligands one by one.
