16.) Which of the following esters reacts fastest under conditions of acid-catalyzed hydrolysis? A) ethyl propanoate...
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...
