1. The problem statement, all variables and given/known data I just wanted to review what happens when methyl benzoate dissolves in sulfuric acid (the ionic species that arise). My workings/reasonings are below. 2. Relevant equations See below. 3. The attempt at a solution After the ester in placed in the acid, the O atom double bonded to the C (C=O group) is protonated by the acid. A series of resonance structures, such as ___OH ___| Ph-C-OCH3 and ___O-H ___|| Ph-C-OCH3 result? Before the O atom is actually protonated, can the following be considered as one of the ions, aside from HSO4-, that are produced? ___O- ___| Ph-C-OCH3 --(+) Are there any other ions that I am missing from this reaction? Thanks.
