Studies on Bunnett & Bunnett Olsen parameters of oxidation of L–aspartic acid, L–valine & L–leucine by SeO2

A. K. Mishra, S. D. Sharma

Abstract :

Bunnett & Bunnett –Olsen data for the oxidation of L–aspartic acid, L–valine & L–leucine by SeO2 have been determined at different concentrations of Sulphuric acid . The rates were found to be increased with increase in acid concentration. Bunnett plots were drawn between log K1 + H0 and log aH2O . The observations indicate no significant information as the plots were not linear but curved. Further, Bunnett – Olsen plots were drawn between log CH+ + H0 & log K1 + H0 . The slope values of Bunnett–Olsen plots were found to be 1.2, 1.0, & 1.0 respectively. These values of slopes indicate participation of water as a proton transferring agent during the course of reactions.
