Preferred Label : synchronous;
IUPAC definition : A concerted process in which the primitive changes concerned (generally bond rupture
and bond formation) have progressed to the same extent at the transition state is
said to be synchronous. The term figuratively implies a more or less synchronized
progress of the changes. However, the progress of the bonding change (or other primitive
changes) has not been defined quantitatively in terms of a single parameter applicable
to different bonds or different bonding changes. The concept is therefore in general
only qualitatively descriptive and does not admit an exact definition except in the
case of concerted processes involving changes in two identical bonds.;
