The oxidation numbers

In ethyne, the bonding electrons of the C-H bond are assigned to the more electronegative carbon. The six electrons of the C-C triple bond are distributed equally to both carbon atoms - pay someone to do my homework . This results in the oxidation number -I for carbon and the oxidation number I for hydrogen.

In a compound, atoms of the same element can have different oxidation numbers, e.g. the carbon atoms in ethanal . The carbon atom to which oxygen is bonded has a higher oxidation number of +I than the carbon atom of the methyl group (OZ -III).

The oxidation numbers can assume values from +VIII to -VIII. An increase in the oxidation number shows that a compound has given up electrons and has thus been oxidised - do my math homework for me . A decrease of an oxidation number corresponds to a reduction by the acceptance of electrons. With the help of the oxidation number model, one can therefore decide whether a certain reaction is a redox reaction. In addition, the oxidation numbers are valuable aids when setting up redox equations.

However, it is not always necessary to set up the Lewis formulae of the compounds to determine the oxidation numbers - do my statistics homework . In most cases, it is sufficient to apply the following rules to determine oxidation numbers.

These simplified rules do not always apply in the case of hydrogen and oxygen. However, they are applicable to almost all simple compounds. The other rules, on the other hand, apply strictly.
