Organic chemistry/Reductions

Reduction is the loss of oxygen from a molecule or the gaining of one or more electrons. A reduction reaction is seen from the point of view of the molecule being reduced, as when one molecule gets reduced another gets oxidised. The full reaction is known as a Redox reaction.

In the case of Organic Chemistry it is usually the case of the gaining/loss of Oxygen/Hydrogen

In Inorganic Chemistry the term refers to the change in oxidation state of the metal center.
