  2. Bromine - Wikipedia

    en.wikipedia.org/wiki/Bromine

    Formally, compounds with this functional group may be considered organic derivatives of the bromide anion. Due to the difference of electronegativity between bromine (2.96) and carbon (2.55), the carbon atom in a C–Br bond is electron-deficient and thus electrophilic.

  3. Bromide - Wikipedia

    en.wikipedia.org/wiki/Bromide

    A bromide ion is the negatively charged form (Br −) of the element bromine, a member of the halogens group on the periodic table.Most bromides are colorless. Bromides have many practical roles, being found in anticonvulsants, flame-retardant materials, and cell stains. [3]

  4. Bromine compounds - Wikipedia

    en.wikipedia.org/wiki/Bromine_compounds

    Due to the difference of electronegativity between bromine (2.96) and carbon (2.55), the carbon atom in a C–Br bond is electron-deficient and thus electrophilic. The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. For many applications, organobromides ...

  5. Molecular solid - Wikipedia

    en.wikipedia.org/wiki/Molecular_solid

    [10] [28] Examples of molecular solids that halogen bond are hexachlorobenzene [11] [29] and a cocrystal of bromine 1,4-dioxane. [27] For the second example, the δ- bromine atom in the diatomic bromine molecule is aligning with the less electronegative oxygen in the 1,4-dioxane. The oxygen in this case is viewed as δ+ compared to the bromine ...

  6. Hydrogen bromide - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_bromide

    Hydrogen bromide is the inorganic compound with the formula HBr.It is a hydrogen halide consisting of hydrogen and bromine. A colorless gas, it dissolves in water, forming hydrobromic acid, which is saturated at 68.85% HBr by weight at room temperature.

  7. Radical (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Radical_(chemistry)

    Homolysis of a bromine molecule producing two bromine radicals. Homolysis makes two new radicals from a spin-paired molecule by breaking a covalent bond, leaving each of the fragments with one of the electrons in the bond. [3] The homolytic bond dissociation energies, usually abbreviated as "ΔH °" are a measure of bond strength.

  8. A value - Wikipedia

    en.wikipedia.org/wiki/A_value

    Bromine, iodine, and chlorine all have similar A-values even though their atomic radii differ. [4] A-values then, predict the apparent size of a substituent, and the relative apparent sizes determine the differences in steric effects between compounds. Thus, A-values are useful tools in determining compound reactivity in chemical reactions.

  9. Sodium bromide - Wikipedia

    en.wikipedia.org/wiki/Sodium_bromide

    Sodium bromide can be used as a source of the chemical element bromine. This can be accomplished by treating an aqueous solution of NaBr with chlorine gas: 2 NaBr + Cl 2 → Br 2 + 2 NaCl
