$XeF_4$

Vedclass · Answer

(A) In the $XeF_4$ molecule,the central atom $Xe$ has $6$ electron pairs in its valence shell,consisting of $4$ bonding pairs and $2$ lone pairs.According to $VSEPR$ theory,the presence of $6$ electron pairs suggests an octahedral geometry.However,due to the presence of $2$ lone pairs,the molecule adopts a square planar geometry to minimize electron-pair repulsions.$XeO_4$ is tetrahedral,$XeO_2F_2$ is see-saw shaped,and $XeOF_4$ is square pyramidal.
