Draw the keto and enol forms of 3,3-dimethylbutan-2-one, circle the more stable tautomer, and propose a mechanism for the conversion of one tautomer to the other in acidic conditions.
Explain why cyclohexa-2,4-dien-1-one (also called 2,4-cyclohexadienone) exists exclusively in the enol form
. Explain why 2,2,4,4-tetramethyl-3-pentanone does not form an enol tautomer
