  2. Electrophilic halogenation - Wikipedia

    en.wikipedia.org/wiki/Electrophilic_halogenation

    The reaction mechanism for chlorination of benzene is the same as bromination of benzene. Iron(III) bromide and iron(III) chloride become inactivated if they react with water, including moisture in the air. Therefore, they are generated by adding iron filings to bromine or chlorine. Here is the mechanism of this reaction:

  3. Hexachlorocyclohexane - Wikipedia

    en.wikipedia.org/wiki/Hexachlorocyclohexane

    Addition of Cl 2 destroys the aromaticity of the benzene ring, and the addition of two more Cl 2 molecules is rapid compared to the first. Hence, only thrice-dichlorinated product can be isolated from this reaction. Radical addition: C 6 H 6 + 3Cl 2 → C 6 H 6 Cl 6. Hexachlorocyclohexane isomers with more than one chlorine atom per carbon are:

  4. Chlorobenzenes - Wikipedia

    en.wikipedia.org/wiki/Chlorobenzenes

    Chlorobenzenes are a group of aryl chlorides/halobenzenes consisting of one or more chlorine atoms as substituents on a benzene core. They have the formula C 6 H 6–n Cl n, where n = 1–6 is the number of chlorine atoms. Depending on the number of chlorine substituents, there may be several constitutional isomers possible. Monochlorobenzene ...

  5. Chlorobenzene - Wikipedia

    en.wikipedia.org/wiki/Chlorobenzene

    Chlorobenzene (abbreviated PhCl) is an aryl chloride and the simplest of the chlorobenzenes, consisting of a benzene ring substituted with one chlorine atom. Its chemical formula is C 6 H 5 Cl. This colorless, flammable liquid is a common solvent and a widely used intermediate in the manufacture of other chemicals.

  6. Electrophilic aromatic substitution - Wikipedia

    en.wikipedia.org/wiki/Electrophilic_aromatic...

    The nitration of benzene is achieved via the action of the nitronium ion as the electrophile. The sulfonation with fuming sulfuric acid gives benzenesulfonic acid. Aromatic halogenation with bromine, chlorine, or iodine gives the corresponding aryl halides. This reaction is typically catalyzed by the corresponding iron or aluminum trihalide.

  7. 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 ...

  8. Photochlorination - Wikipedia

    en.wikipedia.org/wiki/Photochlorination

    In addition to chlorine, sulfur dioxide is also introduced into the reaction mixture. The products formed are alkylsulfonyl chlorides, which are further processed into surfactants. [28] Hydrochloric acid is formed as a coupling product, as is the case with photochlorination. Since direct sulfonation of the alkanes is hardly possible, this ...

  9. Hexachlorobenzene - Wikipedia

    en.wikipedia.org/wiki/Hexachlorobenzene

    In 1867, Henry Bassett proved that the compound produced from benzene and antimony was the same as Julian's carbon chloride and named it "hexachlorobenzene". [10] [9] Leopold Gmelin named it "dichloride of carbon" and claimed that the carbon was derived from cast iron and the chlorine was from crude saltpetre. [9]
