Complete the mechanism for the keto-enol tautomerization shown using bonds, charges, nonbonding electron pairs, and curved arrows (forward reaction only). Do not delete any pre-drawn bonds, charges, or lone pairs. If you accidentally delete a vital part of the structure, click the undo button in the lower left. Step 1: keto form. Draw curved arrows. Step 2: complete the structure, then add curved arrows. Select Draw Rings More Erase Select Draw Rings More Erase H H - H :0: :0: :o: 1L :o:

027 In Part 1 add the curved arrows to the nucleophilic acyl substitution reaction mechanism. In Part 2, answer the multiple-choice question about the reaction in Part 1. Part 1 4 See Periodic Table O See Hint :0: :Br: Add the missing curved arrow notation. S CI Br Part 2 Which statement is most correct regarding the equilibrium for the above reaction? Choose one: O The equilibrium favors the right (i.e., Kea > 1) because acetate is a better leaving group than bromide. O The equilibrium favors the right (i.e., Kea > 1) because bromide is a better leaving group than acetate. O The equilibrium favors the left (i.e., Keq« 1) because acetate is a better leaving group than bromide. O The equilibrium favors the left (i.e., Keg 1) because bromide is a better leaving group than acetate. +
