Question

For square planar complex of platinum (II), ${\left[Pt\left({NH}_3\right)\left(Br\right)\left(Cl\right)py\right]}^0$, how many isomeric forms are possible?

• A. Two
• B. Three
• C. Four
• D. Six

Answer 1

The correct option is B Three

Square planar complexes of the type $\left[MABCD\right]$ occur in three isomeric forms.
Considering one ligand as a reference, here Bromine ($Br$), a total of three isomeric forms of $\left[Pt\right(N{H}_3\left)\right(Br\left)\right(Cl)py{]}^0$ are possible as shown in the figure.

Hence option B is correct.
