Preferred Label : Zucker–Hammett hypothesis;
IUPAC definition : This hypothesis states that, if in an acid catalysed reaction, log 10 k 1 (first-order
rate constant of the reaction) is linear in H0 (Hammett acidity function), water is
not involved in the transition state of the rate-controlling step. However, if log
10 k 1 is linear in log 10 H then water is involved. This has been shown to be incorrect
by Hammett himself.;
