Preferred Label : imbalance;
IUPAC definition : The situation in which reaction parameters that characterize different bond forming
or bond breaking processes in the same reaction have developed to different extents
as the transition state is approached along some arbitrarily defined reaction coordinate.
For example, in the nitroalkane anomaly, the Brønsted β exponent for proton removal
is smaller than the Brønsted α for the nitroalkane, because of imbalance between the
amount of bond breaking and resonance delocalization in the transition state. Imbalance
is common in reactions such as elimination, addition and other complex reactions that
involve proton (hydron) transfer.;
