Kinetic acidity function Hc. Part 3. Applicability to hydration of styrenes

Abstract

Variation of rate of hydration of substituted styrenes with acidity has been measured in aqueous sulphuric acid solutions. This reaction proceeds through a rate-limiting carbon protonation step. Linear Pfluger plots of unit slope result from the data. These appear to validate the applicability of an acidity function to the results; possible sources of error in this and related conclusions are carefully discussed.
