Few researchers studied the alkaline hydrolysis of the ethyl esters of a number of substituted benzoic acids. The m-nitro compound has a rate constant that is 63.5 times as fast as that for the unsubstituted compound. What relative rate constant is predicted for the reaction of p-methoxybenzoate using the Hammett equation? The value based on experimental results is 0.214. The σ value for the m-nitro group is 0.710, and for p-methoxy substitution, the σ value is -0.2.
