# How do you prepare ethyl acetate?

...and add an equivalent amount of ethanol....and give it a good heat at reflux in the presence of small quantities of ${H}_{3} {O}^{+}$..
$\text{H"_3"CCH"_2"OH + HO"_2"CCH"_3stackrel(H_3O^+, Delta)rarr"H"_3"CCH"_2"O"_2"CCH"_3+"H"_2"O}$
Esterification (and there are other methods) is an example of a $\text{condensation reaction}$...to give an addition product with the elimination of a small molecule such as water....the formation of the stable water molecule here serves as a thermodynamic driving force to this reaction...
