Wired Faculty App

The number of geometric isomers that can exist for square planar [Pt (Cl) (py) (NH3) (NH2OH)]+ is (py = pyridine)

  • 2

  • 3

  • 4

  • 6

Solution

B.

3

[Pt (Cl) (py) (NH3) (NH2OH)]+  is square planar complex.
The structures are formed by fixing a group and then arranging all the groups. Hence, this complex shows three geometrical isomers.
