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. http://websites.umich.edu/~chem215/215%20HH%20W11-E2-key.pdf
