  2. IUPAC polymer nomenclature - Wikipedia

    en.wikipedia.org/wiki/IUPAC_polymer_nomenclature

    In the example, there is a bromo-substituted -CH 2-CH 2 - subunit. 1-Bromoethane-1,2-diyl is chosen in preference to 2- bromoethane-1,2-diyl as the former has a lower locant for the bromo-substituent. The preferred CRU is therefore oxy(1-bromoethane-1,2-diyl) and the polymer is thus named poly[oxy(1-bromoethane-1,2-diyl)].

  3. Bromoethane - Wikipedia

    en.wikipedia.org/wiki/Bromoethane

    Bromoethane, also known as ethyl bromide, is a chemical compound of the haloalkanes group. It is abbreviated by chemists as EtBr (which is also used as an abbreviation for ethidium bromide ). This volatile compound has an ether-like odor.

  4. Haloalkane - Wikipedia

    en.wikipedia.org/wiki/Haloalkane

    For example, with bromoethane and sodium hydroxide (NaOH) in ethanol, the hydroxide ion HO − abstracts a hydrogen atom. A Bromide ion is then lost, resulting in ethene, H 2 O and NaBr. Thus, haloalkanes can be converted to alkenes. Similarly, dihaloalkanes can be converted to alkynes.

  5. Radical polymerization - Wikipedia

    en.wikipedia.org/wiki/Radical_polymerization

    In an ethene monomer, one electron pair is held securely between the two carbons in a sigma bond. The other is more loosely held in a pi bond. The free radical uses one electron from the pi bond to form a more stable bond with the carbon atom. The other electron returns to the second carbon atom, turning the whole molecule into another radical.

  6. Bromomethane - Wikipedia

    en.wikipedia.org/wiki/Bromomethane

    In Australia, bromomethane is the preferred fumigant of the Department of Agriculture and Water Resources for most organic goods imported into Australia. [12] The department conducts methyl bromide fumigation certification for both domestic and foreign fumigators who can then fumigate containers destined for Australia.

    For example, ethene + bromine → 1,2-dibromoethane: C 2 H 4 + Br 2 → BrCH 2 CH 2 Br. This takes the form of 3 main steps shown below; [3] Forming of a π-complex The electrophilic Br-Br molecule interacts with electron-rich alkene molecule to form a π-complex 1. Forming of a three-membered bromonium ion
