Abstract

The oxidation and reduction of compounds in organic chemistry can be easily understood by assigning average oxidation numbers to carbon atoms in small or conjugate organic molecules. An atom is negatively charged if it is more electronegative than carbon and positively charged if it is less electronegative than carbon. The oxidation number of an atom is the number of electrons that are accepted or donated by its octet. From the average oxidation numbers of carbon atoms in reactants and products, it can be seen whether small or conjugate organic molecules are oxidized or reduced in the reaction.

  A proposal to define the oxidation state of an atom in a compound as the hypothetical charge of the corresponding atomic ion that is obtained by heterolytically cleaving its bonds such that the atom with the higher electronegativity in a bond is allocated ...

  A variety of approaches to the concept of oxidation and reduction appear in organic textbooks. The method proposed here is different than most published approaches. The oxidation state is calculated by totaling the number of heterogeneous atoms, π-bonds, ...
