Hi, I was wondering if I could get help to understand this question? I have the starting product and then have to get an actual product and I'm not sure if I'm doing this right or why the product is supposed to be a different product because I understand how the mechanism gets to the desired product.

4. Propose two different electron-pushing mechanisms for the following reaction by using one and two electron movements. (hint: rotate the single bonds to align the conformation of the reactant into a product-like structure first.) L HER

Draw the most stable resonance form for the intermediate in the following electrophilic substitution reaction. CI CI HNO3 / H2SO4 O₂N You do not have to consider stereochemistry. • Include all valence lone pairs in your answer. • In cases where there is more than one answer, just draw one. √n [ ?

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. +
