Question

#2 please

con est un cord HgSO4, H2SO4 H20 HBr yout Heat 2. Some mechanism stuff: A. Draw the complete mechanism for reaction C above. B. Draw the enol intermediate for reaction B above. There is a second enol tautomer of the FINAL product of B that can be drawn. It is shown below. Draw a curved arrow mechanism for converting the enol intermediate of reaction B to the enol below, assuming BASIC conditions. HINT: Tautomerization is a reversible process. You will need to go through the final product of B to get from the first enol to the second. Hey, one final question: Of the two enols, which is more stable? Mention two factors that determine relative stability.

Answer 1

HBY H2ö: , Hosas benzylic Proton is very acidie more rotable enol because of extended conjugation with phenyl ming.
