Xenon dioxydifluoride is an inorganic chemical compound with the formula XeO 2 F 2. [ 3 ] [ 2 ] At room temperature it exists as a metastable solid, which decomposes slowly into xenon difluoride , but the cause of this decomposition is unknown.
To prevent decomposition, the xenon tetroxide thus formed is quickly cooled into a pale-yellow solid. It explodes above −35.9 °C into xenon and oxygen gas, but is otherwise stable. A number of xenon oxyfluorides are known, including XeOF 2, XeOF 4, XeO 2 F 2, and XeO 3 F 2. XeOF 2 is formed by reacting OF 2 with xenon gas at
Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.
Xenon oxydifluoride is an inorganic compound with the molecular formula XeOF 2. The first definitive isolation of the compound was published on 3 March 2007, producing it by the previously-examined route of partial hydrolysis of xenon tetrafluoride. [1] XeF 4 + H 2 O → XeOF 2 + 2 HF
Xenon difluoride is a powerful fluorinating agent with the chemical formula XeF 2, and one of the most stable xenon compounds. Like most covalent inorganic fluorides it is moisture-sensitive. It decomposes on contact with water vapor, but is otherwise stable in storage. Xenon difluoride is a dense, colourless crystalline solid.
XeO 2 is a yellow-orange solid. [4] It is an unstable compound, with a half-life of about two minutes, disproportionating into XeO 3 and xenon gas. Its structure and identity was confirmed by cooling it to −150 °C so that Raman spectroscopy could be performed before it decomposed.

It is named after Warren K. Lewis (1882–1975), [6] [7] who was the first head of the Chemical Engineering Department at MIT. Some workers in the field of combustion assume (incorrectly) that the Lewis number was named for Bernard Lewis (1899–1993), who for many years was a major figure in the field of combustion research.
