Characteristic vector analysis of SN1 kinetic data influenced by four variables

Abstract

Characteristic vector analysis has been used to explain the variability in the kinetic data of 1 260 solvolysis reactions caused by four variables. Two characteristic vectors V₁ and V₂ describe the variability with sufficient accuracy. V₁ and V₂ are linearly related to σ₀ substituent constants. S₁′ and S₂′(scalar values after rotation of axes) are linearly dependent on the solvent polarity parameter Y and the reciprocal of the temperature, respectively.
