Abstract

Comparative nucleophilicity of various α-nucleophiles like butane 2, 3-dione monoxime (BDMO), pralidoxime (2-PAM) and benzohydroxamic acid (BHA) towards hydrolysis of pesticide fenitrothion has been measured in the presence of various cationic surfactants at 27°C. It is shown that butane 2, 3-dione monoxime exhibits more reactivity for the degradation of fenitrothion. Effect of alkyl chain length, nucleophile concentration and pH on the rate of reaction of fenitrothion has also been studied.
