  2. Triatomic molecule - Wikipedia

    en.wikipedia.org/wiki/Triatomic_molecule

    Homonuclear triatomic molecules contain three of the same kind of atom. That molecule will be an allotrope of that element. Ozone, O 3 is an example of a triatomic molecule with all atoms the same. Triatomic hydrogen, H 3, is unstable and breaks up spontaneously. H 3 +, the trihydrogen cation is stable by itself and is symmetric.

  3. Organozinc chemistry - Wikipedia

    en.wikipedia.org/wiki/Organozinc_chemistry

    Organozinc compounds were among the first organometallic compounds made. They are less reactive than many other analogous organometallic reagents, such as Grignard and organolithium reagents . In 1848 Edward Frankland prepared the first organozinc compound, diethylzinc , by heating ethyl iodide in the presence of zinc metal. [ 5 ]

  4. Zinc compounds - Wikipedia

    en.wikipedia.org/wiki/Zinc_compounds

    Organozinc compounds contain zinccarbon covalent bonds. Diethylzinc ((C 2 H 5) 2 Zn) was first reported in 1848. It was made by reaction of zinc and ethyl iodide and is the first compound known to contain a metal—carbon sigma bond. [25] For a long time it was a mystery why copper(II) did not form an analogous compound.

  5. Zinc - Wikipedia

    en.wikipedia.org/wiki/Zinc

    Organozinc compounds are those that contain zinccarbon covalent bonds. Diethylzinc ((C 2 H 5) 2 Zn) is a reagent in synthetic chemistry. It was first reported in 1848 from the reaction of zinc and ethyl iodide, and was the first compound known to contain a metal–carbon sigma bond. [70]

  6. Organometallic chemistry - Wikipedia

    en.wikipedia.org/wiki/Organometallic_chemistry

    A steel bottle containing MgCp 2 (magnesium bis-cyclopentadienyl), which, like several other organometallic compounds, is pyrophoric in air.. Organometallic compounds are distinguished by the prefix "organo-" (e.g., organopalladium compounds), and include all compounds which contain a bond between a metal atom and a carbon atom of an organyl group. [2]

  7. Iron oxide - Wikipedia

    en.wikipedia.org/wiki/Iron_oxide

    Electrochemically oxidized iron (rust) An iron oxide is a chemical compound composed of iron and oxygen. Several iron oxides are recognized. Often they are non-stoichiometric. Ferric oxyhydroxides are a related class of compounds, perhaps the best known of which is rust. [1]

  8. Ozonide - Wikipedia

    en.wikipedia.org/wiki/Ozonide

    Tetramethylammonium ozonide, which can be made by a metathesis reaction with caesium ozonide in liquid ammonia, is stable up to 348 K (75 °C): [4] CsO 3 + [(CH 3) 4 N][O 2] → CsO 2 + [(CH 3) 4 N][O 3] Alkaline earth metal ozonide compounds have also become known. For instance, magnesium ozonide complexes have been isolated in a low ...

  9. Oxygen compounds - Wikipedia

    en.wikipedia.org/wiki/Oxygen_compounds

    Most of the organic compounds that contain oxygen are not made by direct action of oxygen. Organic compounds important in industry and commerce are made by direct oxidation of a precursor include: [6] Ethylene oxide (used to make the antifreeze ethylene glycol) is obtained by direct oxidation of ethylene: C 2 H 4 + ½ O 2 + catalyst ...
