    en.wikipedia.org/wiki/Xenon_difluoride

    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.

    3, X = F, Br, Cl, I) via a molecular orbital (MO) description, building on the concept of the "half-bond" introduced by Rundle in 1947. [ 4 ] [ 5 ] In this model, two of the four electrons occupy an all in-phase bonding MO, while the other two occupy a non-bonding MO, leading to an overall bond order of 0.5 between adjacent atoms (see Molecular ...

    en.wikipedia.org/wiki/Xenon_oxydifluoride

    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. The compound has a T-shaped geometry. [1]

    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 low temperatures.

    3) is also based upon a trigonal bipyramid, but the actual molecular geometry is linear with terminal iodine atoms in the two axial positions only and the three equatorial positions occupied by lone pairs of electrons (AX 2 E 3); another example of this geometry is provided by xenon difluoride, XeF 2.

    Xenon tetrafluoride crystals. The binary compounds xenon include xenon difluoride, xenon tetrafluoride, and xenon hexafluoride. [102] Xenon forms several oxyfluorides, such as xenon oxydifluoride, XeOF 2, by hydrolysis of xenon tetrafluoride. [103] Its lighter neighbor, krypton also forms well-characterized compounds, e.g., krypton difluoride.

  8. Xenon tetrafluoride - Wikipedia

    en.wikipedia.org/wiki/Xenon_tetrafluoride

    Xenon tetrafluoride is a chemical compound with chemical formula XeF 4. It was the first discovered binary compound of a noble gas. [3] It is produced by the chemical reaction of xenon with fluorine: [4] [5] Xe + 2 F 2 → XeF 4. This reaction is exothermic, releasing an energy of 251 kJ/mol. [3]

  9. Linear molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Linear_molecular_geometry

    The linear molecular geometry describes the geometry around a central atom bonded to two other atoms (or ligands) placed at a bond angle of 180°. Linear organic molecules , such as acetylene ( HC≡CH ), are often described by invoking sp orbital hybridization for their carbon centers.
