# Is the Fischer Esterification mechanism very simplified?

Example mechanism: Is that very simplified, or is that pretty much what is very likely happening at the molecular/atomic level when you do the reaction in real life? (Of course besides the free $\ce{H+}$, that is obviously hydronium, protonated alcohols, or the acid itself.)

• You can write 8 mechanisms for both esterification and deesterification. As long as the mechanism is reasonable, it has a right to live. – MEL Science Oct 9 '17 at 8:16
