Abstract
The dissociation constants of a series of 28 α-substituted 2-methylpyridinium ions in water at 25 °C have been measured by potentiometric and spectrophotometric methods. Correlation of the −pK values with σI values gives slope ρI = 5.45, intercept −pK0 = −5.81, correlation coefficient r = 0.991, and enables new σI values to be evaluated. Dissociation constants for the 2-pyridinylmethylammonium ion and its N-methyl and N,N-dimethyl derivatives are also reported.
