WebNov 10, 2024 · Transesterification is the conversion of one ester to another via exchange of the alkoxy (OR) groups. It can be performed under both basic and acidic conditions. The mechanism under basic conditions is a … WebThe Fischer esterification proceeds via a carbocation mechanism. In this mechanism, an alcohol is added to a carboxylic acid by the following steps: 1. The carboxyl carbon of the carboxylic acid is protonated. 2. An alcohol molecule adds to the carbocation produced in Step 1. 3. A proton is lost from the oxonium ion generated in Step 2. 4.
