The complex ion $\left[\mathrm{Pt}\left(\mathrm{NO}_{2}ight)(\mathrm{Py})\left(\mathrm{NH}_{3}ight)\left(\mathrm{NH}_{2} \mathrm{OH}ight)ight]$
will give
2 isomers (Geometrical)
3 isomers (Geometrical)
6 isomers (Geometrical)
4 isomers (Geometrical)
Solution
Complexes of the type $\mathrm{M}_{A B C D}$ may exist in three isomeric form. Similarily $\left[\mathrm{Pt}\left(\mathrm{NO}_{2}ight)(\mathrm{Py})\left(\mathrm{NH}_{3}ight)ight.$ $\left.\left(\mathrm{NH}_{2} \mathrm{OH}ight)^{+}ight]$ may exist in three isomeric form.
