To draw resonance structure of the enolate that is formed and to explain why enolate formation is nearly complete when sodium ethoxide is used. Concept introduction: Keto-enol isomerization is possible when a keto group present in the compound has a movable hydrogen atom in the next carbon attached to the carbonyl group. This occurs generally in almost all keto compounds where a chemical equilibria is present between the keto and enol form of the compound. Conversion of keto to its enol form is known as keto-enol tautomerisation. Deprotonation using base results in the formation of enolate ion. If the negative charge is delocalized in more number of atoms that resonance structure is more stable.
