As indicated by the position of ¹⁸O in the product, the acid-catalyzed hydrolysis of t-butyl acetate in water enriched in ¹⁸O does not follow the mechanism for the reverse of Fischer esterification, shown in Figure 19.3. Suggest a mechanism that explains the position of the ¹⁸O in the product and explain why this mechanism is favored in this case.
