Acid catalyzed Fisher

Propose a detailed mechanism for the acid - catalyzed Fisher esterification of propanoic acid and ethanol. Show all resonance forms.

Solution Preview

Please see the attached graphic which shows the complete mechanism with arrows showing electron pushing for the esterification reaction between propanoic acid and ethanol. If you're given another esterification reaction to outline on a test, it will proceed through the same mechanism although the R groups in the acid and alcohol will be different.

Therefore, there are a couple of important ...

Solution Summary

The mechanism of acid-catalyzed Fisher esterification of propanoic acid and ethanol is discussed.
