The number of species having a square planar shape from the following is __________.

XeF4,SF4,SiF4,BF4−,BrF4−,[Cu(NH3)4]2+,[FeCl4]2−,[PtCl4]2−\mathrm{XeF}_{4}, \mathrm{SF}_{4}, \mathrm{SiF}_{4}, \mathrm{BF}_{4}^{-}, \mathrm{BrF}_{4}^{-},\left[\mathrm{Cu}\left(\mathrm{NH}_{3}\right)_{4}\right]^{2+},\left[\mathrm{FeCl}_{4}\right]^{2-},\left[\mathrm{PtCl}_{4}\right]^{2-}

Step-by-Step Verified Solution

XeF4→\mathrm{XeF}_4 \rightarrow Square planar

SF4→\mathrm{SF}_4 \rightarrow See saw

SiF4→\mathrm{SiF}_4 \rightarrow Tetrahedral

BF4−→\mathrm{BF}_4^{-} \rightarrow Tetrahedral

[Cu(NH3)4]2+→\left[\mathrm{Cu}\left(\mathrm{NH}_3\right)_4\right]^{2+} \rightarrow Square planar

[FeCl4]2−→\left[\mathrm{FeCl}_4\right]^{2-} \rightarrow Tetrahedral

[PtCl4]2−→\left[\mathrm{PtCl}_4\right]^{2-} \rightarrow Square planar

BrF4−→\mathrm{BrF}_4^{-} \rightarrow Square planar

So, 4 square planer shape compounds are present.
