  2. Lead(II) fluoride - Wikipedia

    en.wikipedia.org/wiki/Lead(II)_fluoride

    Lead(II) fluoride can be prepared by treating lead(II) hydroxide or lead(II) carbonate with hydrofluoric acid: [3]. Pb(OH) 2 + 2 HF → PbF 2 + 2 H 2 O Alternatively, it is precipitated by adding hydrofluoric acid to a lead(II) salt solution, or by adding a fluoride salt to a lead salt, such as potassium fluoride to a lead(II) nitrate solution, [4]

  3. Fluoroantimonic acid - Wikipedia

    en.wikipedia.org/wiki/Fluoroantimonic_acid

    Fluoroantimonic acid is a mixture of hydrogen fluoride and antimony penta­fluoride, containing various cations and anions (the simplest being H 2 F + and Sb F − 6).This mixture is a superacid that, in terms of corrosiveness, is trillions of times stronger than pure sulfuric acid when measured by its Hammett acidity function.

  5. Perfluoroisobutene - Wikipedia

    en.wikipedia.org/wiki/Perfluoroisobutene

    It is a Schedule 2 substance of the Chemical Weapons Convention. Perfluoroisobutene is highly reactive toward nucleophiles. It hydrolyzes readily to give the relatively innocuous (CF 3) 2 CHCO 2 H, which readily decarboxylates to give hexafluoropropane. It forms addition compounds with thiols, and it is this reactivity that may be related to ...

    In chemical nomenclature, the IUPAC nomenclature of organic chemistry is a method of naming organic chemical compounds as recommended [1] [2] by the International Union of Pure and Applied Chemistry (IUPAC). It is published in the Nomenclature of Organic Chemistry (informally called the Blue Book). [3]

  8. Perfluorinated compound - Wikipedia

    en.wikipedia.org/wiki/Perfluorinated_compound

    Pentafluorophenol, a perfluorinated compound. A perfluorinated compound (PFC) or perfluoro compound is an organofluorine compound that lacks C-H bonds. Many perfluorinated compounds have properties that are quite different from their C-H containing analogues. Common functional groups in PFCs are OH, CO 2 H, chlorine, O, and SO 3 H.
