As the molar mass increases boiling point of the hydrides increases except H2O. . It forms six bonds with the six fluorine atoms because each fluorine atom requires one electron to complete its octet. Why are physically impossible and logically impossible concepts considered separate in terms of probability? All these applications of xenon hexafluoride are because of the presence of lone pairs and six bond pairs. Total valence electrons Kr + 6 (F) that is 8+6(7) = 50. It Is also used in bactericidal lamps, which are used to prepare food. Together, these clearly show that even the second-order JahnTeller approach described earlier is incomplete, as it fails to explain other species valence isoelectronic with $\ce{XeF6}$.
