1. (4 points, 2 points each) For the acid-catalyzed formation of ethyl acetate from acetic acid and ethanol, draw a circle around the structure that cannot be an intermediate. Draw a box around the intermediate formed in the first step of the reaction mechanism. OH OH .C HCOCH2CH3 OH OH H3C-C-OCH2CH3 H3C-C-oCH2CH3 OH OH OH H 2. (2 points) Circle the letter of the carboxylic acid having the lowest pK A O C. O D. O 0 3. (6 points, 2 points each) Consider the following nucleophilic acyl substitution reaction. a. (2 points) Draw the reaction intermediate in the box. b. (2 points) Use curved arrows to show the flow of electrons leading to formation of the intermediate, and to product formation. You must include lone pairs on the atoms involved. (2 points) Is the reaction product-favored or reactant-favored: your answer below, in 50 words or less. Be specific about the reason for your choice. "Because it is more stable" is insufficient. c. Explain
