Xenon oxytetrafluoride (XeOF4) is an inorganicchemical 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:
4 + 2 H
2O → Xe + 4 HF + 3/2 O
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.
