Hydrolysis of o-, m-, and p-tolyl hydrogensuccinates is independent of the type of substrates (∆ E from 17.5 to17.93 kcal mole -1). Similar pH- rate profiles indicate a similar mechanism operating in all these esters, suggesting a polar transition state, The effect of methyl substituent is reflected in different entropies of activation. The order of reactivities is m-ester ≥ p-ester ≥ o-ester.
