Question

How many maximum number of atoms are coplanar in $XeO{F}_4$?

Answer 1

In $XeO{F}_4$, one lone pair of electrons and five bonding domains are present. The hybridization is $s{p}^3{d}^2$. It has square pyramidal structure with the Xenon and four fluorine atoms almost coplanar, the oxygen atom occupies one axial position and the lone pair the other.
