Preferred Label : Grunwald–Winstein equation;
IUPAC definition : The linear free energy relation: \[\log _{10}(\frac{k_{{s}}}{k_{0}}) m\ Y\] expressing
the dependence of the rate of solvolysis of a substrate on ionizing power of the solvent.
The rate constant k0 applies to the reference solvent (ethanol–water, 80:20, v/v)
and ks to the solvent strong s /strong , both at 25 C. The parameter m is characteristic
of the substrate and is assigned the value unity for i tert /i -butyl chloride. The
value Y is intended to be a quantitative measure of the ionizing power of the solvents.
The equation was later extended to the form: \[\log _{10}(\frac{k_{{s}}}{k_{0}})
m\ Y l\ N\] where N is the nucleophilicity of the solvent and l its susceptibility
parameter. The equation has also been applied to reactions other than solvolysis.;
