Carboxylic acid esters can undergo acid catalyzed hydrolysis, neutral hydrolysis and base catalyzed hydrolysis. Below is a table with three structurally related carboxylic acid esters and the second order reaction rate constants for the acid-catalyzed mechanism (k_A) and the rate constant for the base-catalyzed mechanism (k_B). The difference between the three compounds is mainly the substitution of hydrogen atoms on R_1 with the more electronegative chlorine atoms. a) Explain why there is only a small change in k_A for the...

The base-catalyzed hydrolysis of esters can proceed in different pathways depending on the structure of the ester and the solvent, pH and so on. Three types of mechanisms have been suggested, i.e. Bac2 Bal2 and Bal1 mechanisms. Write the detailed steps of each mechanism. Please suggest experiments that can be used to differentiate these mechanisms.(
