1. (4 points, 2 points each) For the acid-catalyzed formation of ethyl acetate from acetic acid and Draw a box around the ethanol, draw a circle around the structure that cannot be an intermediate. intermediate formed in the first step of the reaction mechanism t OH OH H2CH3 H3C OH OH OH OH H 2. (2 points) Circle the letter of the carboxylic acid having the lowest pka A. B. C. O 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 C. ã¼ã¼ã¼ã¼ã¼ã¼ã¼ã¼ã¼. Explain it is more stable" is insufficient
