The kinetics of the reaction of 2-chloro-3-nitropyridine (ortho-like) and 2-chloro-5-nitropyridine (para-like) with a series of aryloxide ions were studied in methanol at different temperatures. Plots of DH โ versus DS โ for both reactions gave good straight lines with isokinetic temperatures of 168

The kinetics of the reactions of 2-chloro-3-nitropyridine (ortho-like) and 5-nitro ( para-like) isomer with morpholine and piperidine were studied in methanol and benzene at several amine concentrations and temperatures in the range 25 -45ยฐC. The data show that k 3-NO 2 /k 5-NO 2 ratios are less tha
