5) In the "reverse" of esterification, esters can be hydrolyzed with aqueous NaOH (as shown below). The factors that influence the rate of ester hydrolysis are similar to those that affect the rate of esterification described above in problem #4. The first step in this mechanism is nucleophilic attack of hydroxide on the carbonyl carbon for form a tetrahedral intermediate, followed by loss of the alcohol.
