The values of the Brønsted exponent for several examples of nucleophilic substitution reactions, aromatic electrophilic substitution reactions, and hydrogen atom abstraction from toluene by free radicals have been calculated from the ρ values of the corresponding reactions. The magnitude of the Brønsted exponent is shown to indicate the degree of charge developed in the transition state structure.
