can someone do 1-3?
Pechmann Condensation 1. Propose a mechanism for the acid-catalyzed Pechmann condensation of resorcinol and ethyl acetoacetate. Identify the transesterification, electrophilic aromatic substitution and dehydration steps. 2. Would you expect 1,3,5-trihydroxybenzene (phloroglucinol) to react more quickly or more slowly than resorcinol? Why or why not? 3. Consider and discuss the greenness of Pechmann Reaction. 4. Discuss and assign the peaks (chemical shift, splitting pattern, etc) in the 1H NMR and IR spectra of your product INDO,

Product was formed successfully based on the exp. below (about
85% yield), please interpret/discuss HNMR/IR in as much detail as
possible and assign peaks on HNMR (which peak represents which
protons of which group, etc). Note: I already know how you
determine the formation of the product so you can skip that part of
part b).
