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.
