Identify the pair of species with same geometries

Identify the pair of species with same geometries
  1. $\mathrm{XeF}_4, \mathrm{PCl}_4^{+}$
  2. $\mathrm{NH}_3, \mathrm{ClF}_3$
  3. $\mathrm{SF}_4, \mathrm{NH}_4^{+}$
  4. $\mathrm{XeF}_2, \mathrm{I}_3^{-}$

Solution

$\mathrm{XeF}_4:$ square planar; $\mathrm{PCl}_4^{+}$: tetrahedral $\mathrm{NH}_3$ : pyramidal; $\quad \mathrm{ClF}_3$; T-shaped $\mathrm{SF}_4$ : see-saw; $\quad \mathrm{NH}_4^{+}$: tetrahedral $\mathrm{XeF}_2:$ Linear; $\quad \mathrm{I}_3^{-}:$Linear
