We know that a carbonyl can react with either acid or base to form an enol. However, it gets interesting when there are substituents at the alpha position. If we start out with a carbonyl and react through either an acid-catalyzed or base-catalyzed mechanism, we form an identical enol in both cases through different intermediates. The base-catalyzed mechanism forms an enolate anion, while the alpha does not. The enol that we form however, changes and becomes . This means that when we react through acid or base-catalyzed mechanisms and go through an enol we will form a mixture if our starting material is and contains an alpha hydrogen at that position.
