Abstract: Both mono- and di-4 chloro, 3-methylphenyle phosphate esters are synthesized by same method called auger and dupes. Phosphate having C-O-P linkage is widely used as fertilizers, pesticides etc. pesticides are generally poisonous or toxic and adversely affected the environment. Study of relative eco-friendly nature of pesticides depends on their bond cleavage and stability during hydrolysis in this connection aand investigation of hydrolysis of 4-Chloro3-Metyl Phenyl Phosphate was carried out by using “Allen’s Modified Method” of colorimetry in aqueous medium from 0.1 to 6.0 mol dm-3 HCl at 98o. Ionic strength data exhibits different contribution of natural species and presence of acid catalysis. Theoretical rates estimated from second empirical term of Debye-Hickel equation have been found in close agreement with experimental rates. The effect of ionic strength, temperature, solvent and concentration are provided to identify the reactive species and molecularity. Bimolecular behavior has been decided by the Arrhenius parameters and by the analysis of molecularity data. The monoester involves P-O Bond fission which is strengthened by comparative kinetic data’s.
