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:

${\rm {2XeOF_{4}+4H_{2}O\longrightarrow 2Xe+8HF+3O_{2}}}$

In addition, some ozone and fluorine are also formed. This 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 a following steps:

${\rm {XeOF_{4}+H_{2}O\longrightarrow XeO_{2}F_{2}+2HF}}$

${\rm {XeO_{2}F_{2}+H_{2}O\longrightarrow XeO_{3}+2HF}}$

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

${\rm {2XeO_{3}\longrightarrow 2Xe+3O_{2}}}$
