  2. Iodide - Wikipedia

    en.wikipedia.org/wiki/Iodide

    An iodide ion is I −. [2] Compounds with iodine in formal oxidation state −1 are called iodides.In everyday life, iodide is most commonly encountered as a component of iodized salt, which many governments mandate.

  3. Hypervalent organoiodine compounds - Wikipedia

    en.wikipedia.org/wiki/Hypervalent_organoiodine...

    Hypervalent iodine oxyanions are known for oxidation states +1, +3, +5, and +7; organic analogues of these moieties are known for each oxidation state except +7. In terms of chemical behavior, λ 3 ‑ and λ 5 ‑iodanes are generally oxidizing and/or electrophilic species. They have been widely applied towards those ends in organic synthesis. [1]

  5. Iodine compounds - Wikipedia

    en.wikipedia.org/wiki/Iodine_compounds

    Most metal iodides with the metal in low oxidation states (+1 to +3) are ionic. Nonmetals tend to form covalent molecular iodides, as do metals in high oxidation states from +3 and above. Both ionic and covalent iodides are known for metals in oxidation state +3 (e.g. scandium iodide is mostly ionic, but aluminium iodide is not).

  6. Iodine oxide - Wikipedia

    en.wikipedia.org/wiki/Iodine_oxide

    Iodine pentoxide (I 2 O 5). Iodine oxides are chemical compounds of oxygen and iodine.Iodine has only two stable oxides which are isolatable in bulk, iodine tetroxide and iodine pentoxide, but a number of other oxides are formed in trace quantities or have been hypothesized to exist.

  7. Iodine value - Wikipedia

    en.wikipedia.org/wiki/Iodine_value

    In chemistry, the iodine value (IV; also iodine absorption value, iodine number or iodine index) is the mass of iodine in grams that is consumed by 100 grams of a chemical substance. Iodine numbers are often used to determine the degree of unsaturation in fats , oils and waxes .

    For example, in the molecules represented by CH 3 X, where X is a halide, the carbon-X bonds have strengths, or bond dissociation energies, of 115, 83.7, 72.1, and 57.6 kcal/mol for X = fluoride, chloride, bromide, and iodide, respectively. [2] Of the halides, iodide usually is the best leaving group.
