1. Conversion of cis 2-butene to trans 2-butene is an example of Isomerization / Oxidation / Tautomerization 1 (2 points) Rearrangement / Your Answer: J. Keto-Enol tautomerization is based on [ Resonance / Hyperconjugation / Bond rotation / Hydride shift 1 (2 points) Your Answer:
There are three metabolically irreversible reactions in glycolysis. Two of these reactions are made irreversible by while the third is made irreversible by _ ATP hydrolysis: ATP synthesis ATP hydrolysis: oxidation ATP hydrolysis: enol to keto tautomerization ATP synthesis: oxidation

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...
Draw the mechanism for the conversion of propanedial in its keto form to its enol form under basic and acidic conditions. Do the same for the conversion from the enol form to the keto form.
Can you change this sentence so I dont get caught for plagerizm Both of the enthalpies are small and positive meaning heat is absorbed. Both the entropies are negative and small, meaing this reaction was nonspontaneous. This reaction is enthalpy driven. The entropy change for the reaction makes sense because the keto configuration is more favored than the enol configuration...
Propose a base catalyzed tautomerization mechanism for the keyo to enol conversion of guanine.
#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...
7.44 Draw the mechanism for the conversion of propanedial (see Problem 7.43) in its keto form to its enol form under basic and acidic conditions. Do the same for the conversion from the enol form to the keto form.
