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:

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

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:

${\displaystyle {\rm {XeOF_{4}+H_{2}O\longrightarrow XeO_{2}F_{2}+2HF}}}$
${\displaystyle {\rm {XeO_{2}F_{2}+H_{2}O\longrightarrow XeO_{3}+2HF}}}$

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

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