Hydrolysis of Phosphoric p-MeOptienylamide has been kinetically pursued in 0.01-7.0M, HCl media at 40°C (± 0.5). The Zwitterion (or the modified - Neutral) form functions at low acid (0.01 - 0.5M, HCl) molarities while the Neutral form makes an almost constant contribution between 1.0 to 4.0M, HCl. The Monoprotonated species, however, operates in the entire acid range (0.01 - 7.0M, HCl). Neutral electrolyte effect study also favours specific acid catalysis with a +ve ionic strength effect. Arrhenius Parameters’ determination, D2O effect and various correlations strengthen a bimolecular mode of hydrolysis in the entire acid region, leading to 3 mechanic routes in all.
