Compelling evidence for the existence of a tetrahedral intermediate innucleophilic acyl substitution was obtained in a series of elegantexperiments carried out by Myron Bender in 1951. The key experimentwas the reaction of aqueous −OH with ethyl benzoate (C6H5COOCH2CH3)labeled at the carbonyl oxygen with 18O. Bender did not allow thehydrolysis to go to completion, and then examined the presence of alabel in the recovered starting material. He found that some of therecovered ethyl benzoate no longer contained a label at the carbonyloxygen. With reference to the accepted mechanism of nucleophilic acyl substitution, explain how this provides evidence for a tetrahedralintermediate.
