The reaction of the acetic anhydride with the alcohol, in the presence of acid, to form the ester is carried out in a reaction flask that is connected to a condenser (as shown below)

As the reaction flask is heated and the solvent in the reaction flask is converted to vapour, the condenser allows water to surround the inner glass column. This cools the solvent vapour inside the column and the vapour condenses and returns to the reaction flask. This is important so that the reaction flask does not boil dry. Which of the following explanations is the most important reason for attaching the inlet of water to the bottom of the condenser and not the top.
