what is the relationship between keto and enol of acetone?
The deprotonated form of an enol is an enolate. As a general rule, the keto form of a carbonyl is lower in energy, and thus predominates at equilibrium. Acetone, for example, is present at >99% keto form at equilibrium. Exercise 13.1: Draw all of the possible enol forms of the following aldehydes/ketones.
