In the XeF4 lewis structure, there are more than 8 valence electrons which include 2 lone pairs and the bonding electrons. There are three lone pairs on each fluorine atom. Im not sure this is right, but I think Al doesnt form any double bonds in AlH3 since it has such a low electronegativity. However, Xenon is seen to have more than eight valence electrons i.e. Also, it has octahedral electron geometry. Therefore, each fluorine atom now has a complete octet i.e. What is the electron pair geometry of this molecule? However, we also notice that all the atoms of this molecule contain one or more lone pairs of electrons. Taking the above values into consideration the following chart is used to estimate the molecular geometry of a compound as per the VSEPR theory: As per the above chart, the XeOF4 molecule which has 5 bond pairs and one lone pair attached to the central atom should have square pyramidal geometry.
