# Esterification and dehydration synthesis

I know there are many more terms out there like polymerization, condensation, etc. But the important thing is whether they can be differentiated or not.

In Esterification, which I just learned, needs to have a dehydrating agent when involving bad leaving group, such as $\ce{-OH}$.They are typically Brønsted-Lowry acids. Correct me if I'm wrong.

How does heterolysis work in the case of $\ce{CH3COOC2H5}$. [the reverse of the esterification of ethanoic acid and ethanol]
