Mechanism. (Similar to Smith, 20.72) The existernce of a tetrahedral intermediate in nucleophilic acyl substitution is supported by a series of experiments carried out by Myron Bender in 1951. In the key experiment, Bender carried out the following base catalyzed hydrolysis of ethyl benzoate, where the carbonyl oxygen was labeled with 1O. Bender recovered some starting material from this reaction mixture where the carbonyl oxygen was no longer labeled. Propose a mechanism that explains this observation. 180 NaOH Hо Mechanism...

Paragraph Styles 6. ... 7 1. Why is an ester less reactive to nucleophilic acyl substitution than an acid chloride? A) Chloride is a better leaving group B) Oxygen is better at donating electron density into the carbonyl with added resonance stability. C) Chloride is a better leaving group and compared to chlorine, oxygen is better at donating electron density into the carbonyl with added resonance stability D) The alkoxy anion is less basic than the chloride anion. 2. What...
