The
orbital symmetry control of concerted reactions; this requires
transformation of the molecular orbitals of reactants into those of products to proceed continuously
by following a
reaction path along which the symmetry of these orbitals remains unchanged. Reactions which adhere
to this requirement are classified as symmetry-allowed reactions, and those which
do not as symmetry-forbidden reactions.
