Which of the following esters is more reactive (the better electrophile)? Explain your answer و همیم
(7 points) Explain why esters are more reactive towards nucleophilic acyl substitution compared to amides. Your answer should be clear and concise. Writing more than necessary only increases the odds of writing an incorrect statement, which could result in points off. nucleophilic acyl substitution Nu R X R Nu - - - - - - - - - - O RO R NO Ester Amide
Which electrophile is LEAST reactive with a nucleophile? H -OH

3. Give a brief explanation why acid chlorides are more reactive than esters in a nucleophilic substitution reaction, like a polymerization. Grading Scheme
Which of the following statements is NOT true about acid anhydrides? A. Acid anhydrides are more reactive than esters but less reactive than acyl chlorides. B. An acid anhydride reacts with water to form an ester product. C. Acid anhydrides eliminate a carboxylate ion as a leaving group. D. An acid anhydride is considered to have a better leaving group (i.e. weaker base) than the leaving groups of esters, carboxylic acids, and amides. A B C D
8. Which element in each pair is MORE reactive? Explain your choice on the basis of IE, EA, or other. a. Pb or Cs b. Ca or Ba c. Si or Pa d. F2 or N2
