Question

Which has square planar geometry?

• A. $Pt{\left({NH}_3\right)}_2{Cl}_2$
• B. ${\left[Ni{\left(CN\right)}_4\right]}^{2-}$
• C. Both (a) and (b)
• D. None of these

Answer 1

The correct option is C Both (a) and (b)

Valence shell configuration of ${Pt}^{2+}$ in $\left[Pt{\left({NH}_3\right)}_2{Cl}_2\right]$ is shown
The resulting complex is square planar
Valence shell electronic configuration of ${Ni}^{2+}$ in ${\left[Ni{\left(CN\right)}_4\right]}^{2-}$ is shown
The resulting complex is square planar.
