  2. Bromopentane - Wikipedia

    en.wikipedia.org/wiki/Bromopentane

    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.

  3. Isotopes of bromine - Wikipedia

    en.wikipedia.org/wiki/Isotopes_of_bromine

    Bromine-77 is the most stable radioisotope of bromine, with a half-life of 57 hours. [13] Although β + decay is possible for this isotope, about 99.3% of decays are by electron capture. [ 9 ] Despite its complex emission spectrum, featuring strong gamma-ray emissions at 239, 297, 521, and 579 keV, [ 14 ] 77 Br was used in SPECT imaging in the ...

  6. Isomer - Wikipedia

    en.wikipedia.org/wiki/Isomer

    Isomer. In chemistry, isomers are molecules or polyatomic ions with identical molecular formula – that is, the same number of atoms of each element – but distinct arrangements of atoms in space. [1] Isomerism refers to the existence or possibility of isomers.

  7. Isotopes of carbon - Wikipedia

    en.wikipedia.org/wiki/Isotopes_of_carbon

    Carbon (6 C) has 14 known isotopes, from 8 C to 20 C as well as 22 C, of which 12 C and 13 C are stable.The longest-lived radioisotope is 14 C, with a half-life of 5.70(3) × 10 3 years. . This is also the only carbon radioisotope found in nature, as trace quantities are formed cosmogenically by the reactio

  8. Structural isomer - Wikipedia

    en.wikipedia.org/wiki/Structural_isomer

    Structural isomer. In chemistry, a structural isomer (or constitutional isomer in the IUPAC nomenclature [1]) of a compound is another compound whose molecule has the same number of atoms of each element, but with logically distinct bonds between them. [2][3] The term metamer was formerly used for the same concept. [4]

  9. Bromine compounds - Wikipedia

    en.wikipedia.org/wiki/Bromine_compounds

    Bromine compounds are compounds containing the element bromine (Br). These compounds usually form the -1, +1, +3 and +5 oxidation states. Bromine is intermediate in reactivity between chlorine and iodine, and is one of the most reactive elements. Bond energies to bromine tend to be lower than those to chlorine but higher than those to iodine ...
