4. Conversion of B into C involves hydrolysis of the ester followed by decarboxylation. On the structures provided below, show the electron flow for the decarboxylation step. CH2Ph 5. The initial product formed on decarboxylation is an enol, which rapidly equilibrates to its keto form under the acidic reaction conditions. Write the complete stepwise mechanism for the acid-catalyzed conversion of the enol into its keto form, Compound C. Ph Ph

please don't use any abbreviations! like I
don't know how to draw anything like oet or an R group like please
just draw out the whole thing!
CH3 CO2Et Hagemann's ester The compound known as Hagemann's ester is prepared by treatment of a mixture of formaldehyde and ethyl acetoacetate with base, followed by acid-catalyzed decarboxylation. The reaction involves the following steps: 1. Deprotonation of ethyl acetoacetate to form enolate ion 1; 2. Reaction of the enolate ion with formaldehyde to...
