Question:

When acetone is dissolved in water containing 18O instead of ordinary 16O (i.e., H2 18O instead of H2 16O), the acetone soon begins to acquire 18O and becomes

The formation of this oxygen-labeled acetone is catalyzed by traces of strong acids and by strong bases (e.g., HO-). Show the steps that explain both the acid-catalyzed reaction and the base-catalyzed reaction.
