Preferred Label : reactivity index;
IUPAC definition : Any numerical index derived from quantum mechanical model calculations that permits
the prediction of relative reactivities of different molecular sites. Many indices
are in use, based on a variety of theories and relating to various types of reaction.
The more successful applications have been to the substitution reactions of conjugated
systems where relative reactivities are determined largely by changes of π-electron
energy.;
