| Abstract: | Kinetic solvent effects on hydrolysis of hydroxamic acids of the type R.N (OH). C=O.R'[R=H; R'=CH3, C6H5, C6H4-OH; R=CH3-C6H4Rʹ = C6H5] in aqueous mixtures (10-70% v/v) of some polar protic, polar aprotic and low polarity basic solvents have been studied. The solvatochromic parameters α for the hydrogen-bond-donating ability, β, for the hydrogen-bond- accepting ability and, π*, for the dipolarity/polarizability and linear solvation energy relationships have been used to quantify solvent effects. Kamlet and Taft's triparametric equation explain the greater than 70% of the effect of solvent on the hydrolysis. The other parameters i.e., D, ET and Z have also been used. |
