In an addition reaction the number of σ-bonds in the substrate molecule increases, usually at the expense of one or more π-bonds. The reverse is true of elimination reactions, i.e.the number of σ-bonds in the substrate decreases, and new π-bonds are often formed.Substitution reactions, as the name implies, are characterized by replacement of an atom or group (Y) by another atom or group (Z).
