To draw two possible enols for 3-methyl-2-butanone and to show a mechanism of base catalyzed conversion for each enol. 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. The conversion of keto to its enol form is known as keto-enol tautomerisation. Please note that if two α hydrogen are present in the keto compound, two enols can be formed.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone
