  2. 1-Bromobutane - Wikipedia

    en.wikipedia.org/wiki/1-Bromobutane

    1-Bromobutane is the organobromine compound with the formula CH 3 (CH 2) 3 Br. It is a colorless liquid, although impure samples appear yellowish. It is insoluble in water, but soluble in organic solvents. It is primarily used as a source of the butyl group in organic synthesis. It is one of several isomers of butyl bromide.

  3. 2-Bromobutane - Wikipedia

    en.wikipedia.org/wiki/2-Bromobutane

    2-Bromobutane is an isomer of 1-bromobutane. Both compounds share the molecular formula C 4 H 9 Br. 2-Bromobutane is also known as sec -butyl bromide or methylethylbromomethane. Because it contains bromine , a halogen, it is part of a larger class of compounds known as alkyl halides .

  4. Bromobutane - Wikipedia

    en.wikipedia.org/wiki/Bromobutane

    Bromobutane (molecular formula: C 4 H 9 Br, molar mass: 137.02 g/mol) may refer to either of two chemical compounds: 1-Bromobutane (n-butyl bromide)

  5. Bromopentane - Wikipedia

    en.wikipedia.org/wiki/Bromopentane

    Bromopentanes are a group of bromoalkanes consisting of pentane isomers with one or more hydrogen atoms replaced by bromine atoms. They have the formula C 5 H 12–n Br n, where n = 1–12 is the number of bromine atoms. They are colorless liquids.

  6. Isomerization - Wikipedia

    en.wikipedia.org/wiki/Isomerization

    In certain kinds of alkene polymerization reactions, chain walking is an isomerization process that introduces branches into growing polymers. [citation needed] The trans isomer of resveratrol can be converted to the cis isomer in a photochemical reaction. [6] Thermal rearrangement of azulene to naphthalene has been observed. [7]

  7. C4H9Br - Wikipedia

    en.wikipedia.org/wiki/C4H9Br

    The molecular formula C 4 H 9 Br, (molar mass: 137.02 g/mol, exact mass: 135.9888 u) may refer to: 1-Bromobutane; 2-Bromobutane; tert-Butyl bromide;

  8. n-Butyllithium - Wikipedia

    en.wikipedia.org/wiki/N-Butyllithium

    The standard preparation for n-BuLi is reaction of 1-bromobutane or 1-chlorobutane with Li metal: [3] 2 Li + C 4 H 9 X → C 4 H 9 Li + LiX (X = Cl, Br) If the lithium used for this reaction contains 1–3% sodium, the reaction proceeds more quickly than if pure lithium is used.

    [2] [3] [4] The ring-flip of substituted cyclohexanes constitutes a common form of conformers. [5] The study of the energetics of bond rotation is referred to as conformational analysis. [6] In some cases, conformational analysis can be used to predict and explain product selectivity, mechanisms, and rates of reactions. [7]
