Question

When a ketone and its enol are in equilibrium, under most conditions the concentration of the enol is ________ the concentration of the ketone?

Answer 1

Much lower than ketone is more stable than enol. N, 4-Dimethylpent -4-en-2-Amine (NH_3 protonated in acidic protoned in acidic conditions) d. [Proton cannot re extracted from OH in acidic conditions to firm O^(-)].

Answer 2

When a ketone and its enol are in equilibrium, under most conditions the concentration of the enol is much lower than the concentration of the ketone. This chemical equilibrium is called the keto-enol tautomerism. The keto would be in rapid equilibrium with the enol tautomer. And in this equilibrium the keto form is much stable so it predominates in the mixture. So, the concentration of the enol would be lower than that of the keto.
