Xenon oxytetrafluoride (XeOF₄) is an inorganic chemical compound. As are most xenon oxides, it is extremely reactive and unstable, and hydrolyses in water to give dangerously hazardous and corrosive products, including hydrogen fluoride:

$\rm 2XeOF_4 + 4 H_2O \longrightarrow 2Xe + 8HF + 3O_2$

In addition, some ozone and fluorine are also formed. The reaction is extremely dangerous, and xenon oxytetrafluoride should therefore be kept away from any trace of water or water vapour under all conditions.

Reactions

XeOF₄ reacts with H₂O in the following steps:

$\rm XeOF_4 + H_2O \longrightarrow XeO_2F_2 + 2HF$

$\rm XeO_2F_2 + H_2O \longrightarrow XeO_3 + 2HF$

XeO₃ is a dangerous explosive, decomposing explosively to Xe and O₂:

$\rm 2XeO_3 \longrightarrow 2Xe + 3O_2$
