Xenon oxytetrafluoride (XeOF4) is an inorganic chemical compound. As are all xenon compounds, it is extremely reactive and unstable, and hydrolyses in water to give dangerously hazardous and corrosive products, including hydrogen fluoride:
- XeOF
4 + 2 H
2O → Xe + 4 HF + 3/2 O
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:
- XeOF
4 + H
2O → XeO
2F
2 + 2 HF
- XeO
2F
2 + H
2O → XeO
3 + 2 HF
XeO3 is a dangerous explosive, decomposing explosively to Xe and 3/2 O2.
