question 1 and 3 can you form an enolate ion under acidic conditions? If so, provide...
O4 04 H 3 Some compounds can form more than one enol tautomer. Draw all the possible enol tautomers for the following compounds. OEt 이1 OH OH 4 Circle the side of the reaction favored at equilibrium. (lot audic) OH + H20 H H pKa 15.7 pКа в 17 tBuO + tBuOH + pКa 3 9 pKa 17
a. Caffeine can be protonated under acidic conditions to form an imidazolium-like species. Draw the structure for this protonated form, then find and report a pKa value for the most acidic proton. b. Draw a reaction scheme between caffeine and water. Which side of the equilibrium is favored for this acid/base reaction? Hint: Use the pKa value from part a. c. Find and report a pKa value for phenol. Draw a reaction scheme between phenol and water. Which side of...
please help The dehydration of alcohols Under acidic conditions, alcohols will undergo a dehydration reaction, producing an alkene and water. During the reaction, the hydroxyl group of the alcohol and a hydrogen atom from an adjacent carbon atom are lost. The reaction takes place in three steps, as shown in the diagram. (Figure 1) In the first step, a hydrogen lon bonds to the hydroxyl group of the alcohol. In the second step, the protonated hydroxl group leaves the compound,...
