  2. Chlorine - Wikipedia

    en.wikipedia.org/wiki/Chlorine

    Corresponding to periodic trends, it is intermediate in electronegativity between fluorine and bromine (F: 3.98, Cl: 3.16, Br: 2.96, I: 2.66), and is less reactive than fluorine and more reactive than bromine. It is also a weaker oxidising agent than fluorine, but a stronger one than bromine.

  3. Bromine compounds - Wikipedia

    en.wikipedia.org/wiki/Bromine_compounds

    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, and bromine is a weaker oxidising agent than chlorine but a stronger one than iodine.

  4. Bromine - Wikipedia

    en.wikipedia.org/wiki/Bromine

    Bond energies to bromine tend to be lower than those to chlorine but higher than those to iodine, and bromine is a weaker oxidising agent than chlorine but a stronger one than iodine. This can be seen from the standard electrode potentials of the X 2 /X − couples (F, +2.866 V; Cl, +1.395 V; Br, +1.087 V; I, +0.615 V; At, approximately +0.3 V).

  5. Halogenation - Wikipedia

    en.wikipedia.org/wiki/Halogenation

    Bromine is a weaker halogenating agent than both fluorine and chlorine, while iodine is the least reactive of them all. The facility of dehydrohalogenation follows the reverse trend: iodine is most easily removed from organic compounds, and organofluorine compounds are highly stable.

  6. Reactivity–selectivity principle - Wikipedia

    en.wikipedia.org/wiki/Reactivity–selectivity...

    Whereas the relatively unreactive bromine reacts with 2-methylbutane predominantly to 2-bromo-2-methylbutane, the reaction with much more reactive chlorine results in a mixture of all four regioisomers. Another example of RSP can be found in the selectivity of the reaction of certain carbocations with azides and water.

  7. Biological roles of the elements - Wikipedia

    en.wikipedia.org/wiki/Biological_roles_of_the...

    bromine: 35: 5: Essential to membrane architecture and tissue development in animals. [23] May have antibiotic effects in some compounds when it substitutes for chlorine. [24] Bromine compounds are very common in and presumably essential to a variety of marine organisms, including bacteria, fungi, seaweeds, and diatoms.

  8. Frost diagram - Wikipedia

    en.wikipedia.org/wiki/Frost_diagram

    The Frost diagram normally shows free-energy values above and below nE° = 0 and is scaled in integers. The y axis of the graph displays the free energy. Increasing stability (lower free energy) is lower on the graph, so the higher free energy and higher on the graph a species of an element is, the more unstable and reactive it is. [2]

  9. Interhalogen - Wikipedia

    en.wikipedia.org/wiki/Interhalogen

    Chlorine trifluoride has a boiling point of −12 °C. Bromine trifluoride has a boiling point of 127 °C and is a liquid at room temperature. Iodine trichloride melts at 101 °C. [1] Most interhalogens are covalent gases. Some interhalogens, especially those containing bromine, are liquids, and most
