  2. Halide - Wikipedia

    en.wikipedia.org/wiki/Halide

    radii of common halogen atoms (gray/black) and the corresponding halide anions (blue) In chemistry, a halide (rarely halogenide [1]) is a binary chemical compound, of which one part is a halogen atom and the other part is an element or radical that is less electronegative (or more electropositive) than the halogen, to make a fluoride, chloride, bromide, iodide, astatide, or theoretically ...

  3. Metal halides - Wikipedia

    en.wikipedia.org/wiki/Metal_halides

    Halide ligands may also be displaced by the alkali salt of an X-type ligand, such as a salen-type ligand. [10] This reaction is formally a transmetallation, and the abstraction of the halide is driven by the precipitation of the resultant alkali halide in an organic solvent. The alkali halides generally have very high lattice energies.

  4. Hydrogen halide - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_halide

    In chemistry, hydrogen halides (hydrohalic acids when in the aqueous phase) are diatomic, inorganic compounds that function as Arrhenius acids. The formula is HX where X is one of the halogens: fluorine, chlorine, bromine, iodine, astatine, or tennessine. [1] All known hydrogen halides are gases at standard temperature and pressure. [2]

  5. Alkali metal halide - Wikipedia

    en.wikipedia.org/wiki/Alkali_metal_halide

    Alkali metal halides, or alkali halides, are the family of inorganic compounds with the chemical formula MX, where M is an alkali metal and X is a halogen. These compounds are the often commercially significant sources of these metals and halides. The best known of these compounds is sodium chloride, table salt. [1]

  6. Category:Halides - Wikipedia

    en.wikipedia.org/wiki/Category:Halides

    Halides are compounds containing halogens. The halogens may either be bonded to another element through covalent bonding or (as in many metal halides) present in the form of the halide ion . Subcategories

  7. Coupling reaction - Wikipedia

    en.wikipedia.org/wiki/Coupling_reaction

    In one important reaction type, a main group organometallic compound of the type R-M (where R = organic group, M = main group centre metal atom) reacts with an organic halide of the type R'-X with formation of a new carbon-carbon bond in the product R-R'. The most common type of coupling reaction is the cross coupling reaction.

  8. Acyl halide - Wikipedia

    en.wikipedia.org/wiki/Acyl_halide

    Acyl halides are rather reactive compounds often synthesized to be used as intermediates in the synthesis of other organic compounds. For example, an acyl halide can react with: water, to form a carboxylic acid. This hydrolysis is the most heavily exploited reaction for acyl halides as it occurs in the industrial synthesis of acetic acid.

  9. Vinyl halide - Wikipedia

    en.wikipedia.org/wiki/Vinyl_halide

    General structure of a vinyl halide, where X is a halogen and R is a variable group. In organic chemistry, a vinyl halide is a compound with the formula CH 2 =CHX (X = halide). The term vinyl is often used to describe any alkenyl group. For this reason, alkenyl halides with the formula RCH=CHX are sometimes called vinyl halides.
