• atoms
  • Halogenation of Alkenes is explained as an electrophylic addition followed by the formation of halonium ion which reacts with neuleophilic halogen ion yielding a vicinal dihalide (two halide groups on adjacent carbon atoms). (dailymotion.com)
  • Many oxidations involve removal of hydrogen atoms from the organic molecule, and the reverse, reduction adds hydrogens to an organic molecule. (wikipedia.org)
  • In relation to the oxide or halide, for a given oxidation state of an element A, if two halogen atoms replace one oxygen atom, or vice versa, the overall charge on the molecule is unchanged and the coordination number of the central atom decreases by one. (wikipedia.org)
  • electrons
  • In oxidations electrons are removed and the electron density of a molecule is reduced. (wikipedia.org)
  • A pair of π bonds arises from overlap of filled d-orbitals on the metal with a pair of π-antibonding orbitals projecting from the carbon atom of the CO. The latter kind of binding requires that the metal have d-electrons, and that the metal is in a relatively low oxidation state ( (wikipedia.org)
  • state
  • In this example, the oxidation state increases by two and the electrical charge is unchanged. (wikipedia.org)
  • For example, both phosphorus oxychloride, POCl3 and phosphorus pentachloride, PCl5 are neutral covalent compounds of phosphorus in the +5 oxidation state. (wikipedia.org)
  • similar
  • Oxohalides of elements in high oxidation states are strong oxidizing agents, with oxidizing power similar to the corresponding oxide or halide. (wikipedia.org)
