Question

Draw the molecular structures of XeF₂, XeF₄ and XeO₂F₂, indicating the location of lone pair (s) of electrons.

Answer 1

In it Xe is sp³ d-hybridised but its shape is linear due to involvement of VSEPR theory. (ie, due to presence of three free pair of electrons, geometry of XeF₂ is distorted from trigonal bipyramidal to linear)

trn it Xe is sp³ d²-hybridised but its shape is square planar due to involvement of VSEPR theory. (ie, due to presence of two free pair of electrons, geometry of XeF₄ is distorted from octahedral to square planar).

In it Xe is sp³ d-hybrid, but its geometry is Planar due to involvement of VSEPR theory. (ie, due to presence of a free pair  of electrons, its geometry is distorted from trigonal bipyramidal to planar.)
