(20 pts.) Give а full curved аrrоw-pushing mechаnism fоr cоnversion of the enol into its keto form, under base-catalyzed conditions, as shown below. Indicate the Lewis acid and base at each step (use the LA and LB notation) as appropriate, and whether they are also Bronsted acids/bases (use the BA and BB notation). Include all relevant resonance contributors. To preview image: Click Here
