Q. The number of geometric isomers that can exist for square planar $\left[ Pt ( Cl )( py )\left( NH _{3}\right)\right.$ $\left.\left( NH _{2} OH \right)\right]^{+}$ is $( py =$ pyridine $):$

Solution:

$\left[ Pt ( Cl )( py )\left( NH _{3}\right)\left( NH _{2} OH \right)\right]^{+}$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
