Oxygen monofluoride is an unstable binary inorganic compound radical of fluorine and oxygen with the chemical formula OF.[1][2][3] This is the simplest of many oxygen fluorides.
Synthesis
[edit]OF is a radical that can be formed by thermal or photolytic decomposition of OF
2[4]
- OF2 → OF + F
or a reaction of fluorine and ozone:[5]
- F + O3 → OF + O2
Atmosphere
[edit]Oxygen- and fluorine-containing radicals like OF and O2F occur in the atmosphere. These and other halogen radicals have been implicated in the destruction of ozone in the atmosphere.
- O3 + F → O2 + OF
- O + OF → O2 + F
However, oxygen monofluoride radicals are assumed to not play as big a role in the ozone depletion because free fluorine atoms in the atmosphere are believed to react with methane to produce hydrogen fluoride, which precipitates in rain as hydrofluoric acid.[6]
