Chemistry - CHEMICAL BONDING Question with Solution | TestHub

Tetrahedral structure is associated with$\mathrm{s}{\mathrm{p}}^3$hybridized central atom with 4 bond pairs of electrons and without any lone pair of electrons.
Here$\mathrm{B}{\mathrm{F}}_4^{-}$is Tetrahedral in structure as it has 4 bond pairs of electrons

The shapes of$\mathrm{S}{\mathrm{F}}_4$,$[\mathrm{N}\mathrm{i}{\left(\mathrm{C}\mathrm{N}\right)}_4{]}^{2-}$and$\mathrm{X}\mathrm{e}{\mathrm{F}}_4$are sea-saw, square planar and square planar respectively.
