Question

Find the number of lone pairs of electrons on $Xe$ in $XeO{F}_4.$

Answer 1

One lone pair of electrons is present on Xe in $XeO{F}_4.$
$Xe$ has eight valence electrons out of which four are shared with $4$ electrons of $4F$ atoms. $2$ electrons of $Xe$ are shared with $2$ electrons of $O$ atom. Thus, only one lone pair of electrons is remaining on $Xe$ atom.
