  2. Hydrohalogenation - Wikipedia

    en.wikipedia.org/wiki/Hydrohalogenation

    A hydrohalogenation reaction is the electrophilic addition of hydrogen halides like hydrogen chloride or hydrogen bromide to alkenes to yield the corresponding haloalkanes. [ 1 ] [ 2 ] [ 3 ] If the two carbon atoms at the double bond are linked to a different number of hydrogen atoms, the halogen is found preferentially at the carbon with fewer ...

  3. Swarts fluorination - Wikipedia

    en.wikipedia.org/wiki/Swarts_fluorination

    Swarts fluorination is a process whereby the chlorine atoms in a compound – generally an organic compound, but experiments have been performed using silanes – are replaced with fluorine, by treatment with antimony trifluoride in the presence of chlorine or of antimony pentachloride. Some metal fluorides are particularly more useful than ...

  4. Free-radical halogenation - Wikipedia

    en.wikipedia.org/wiki/Free-radical_halogenation

    The relative rates at which different halogens react vary considerably: [citation needed] fluorine (108) > chlorine (1) > bromine (7 × 10 −11) > iodine (2 × 10 −22).. Radical fluorination with the pure element is difficult to control and highly exothermic; care must be taken to prevent an explosion or a runaway reaction.

  5. Haloalkane - Wikipedia

    en.wikipedia.org/wiki/Haloalkane

    Only haloalkanes that contain chlorine, bromine, and iodine are a threat to the ozone layer, but fluorinated volatile haloalkanes in theory may have activity as greenhouse gases. Methyl iodide , a naturally occurring substance, however, does not have ozone-depleting properties and the United States Environmental Protection Agency has designated ...

  6. Halogen addition reaction - Wikipedia

    en.wikipedia.org/wiki/Halogen_addition_reaction

    A halogen addition reaction is a simple organic reaction where a halogen molecule is added to the carbon–carbon double bond of an alkene functional group. [1] The general chemical formula of the halogen addition reaction is: C=C + X 2 → X−C−C−X (X represents the halogens bromine or chlorine, and in this case, a solvent could be CH 2 ...

  7. Halocarbon - Wikipedia

    en.wikipedia.org/wiki/Halocarbon

    Halocarbon compounds are chemical compounds in which one or more carbon atoms are linked by covalent bonds with one or more halogen atoms (fluorine, chlorine, bromine or iodine – group 17) resulting in the formation of organofluorine compounds, organochlorine compounds, organobromine compounds, and organoiodine compounds.

  8. Finkelstein reaction - Wikipedia

    en.wikipedia.org/wiki/Finkelstein_reaction

    The classic Finkelstein reaction entails the conversion of an alkyl chloride or an alkyl bromide to an alkyl iodide by treatment with a solution of sodium iodide in acetone. Sodium iodide is soluble in acetone while sodium chloride and sodium bromide are not; [ 3 ] therefore, the reaction is driven toward products by mass action due to the ...

  9. Transhalogenation - Wikipedia

    en.wikipedia.org/wiki/Transhalogenation

    A common method is halide metathesis. An example is the conversion of alkyl chloride into alkyl fluoride: . C 3 H 5-Cl + NaF → R-F + NaCl. This kind of reaction is called Finkelstein reaction. [2]
