Chemistry 14D Fall 2008 Final Exam Part A Page 1 For any question (or part of a question) on either part of this exam worth three or more points, you have two choices: answer the question as written or you may write and circle the phrase “one point”. If you write “one point” you will receive one point (and only one point) of credit for the question. “One point” overrides anything you have written for that question, regardless of its accuracy. Example: (10) Briefly explain everything about organic chemistry. OK to use ‘Ph’ and other common abbreviations anywhere in this exam where appropriate. 1. (6) In general, the reaction of any amide with water is quite slow. Using ten words or less in each case , list three distinct different features of the reactants, mechanisms, or products that account for this. Feature #1 : Feature #2 : Feature #3 : 2. (10) For each reaction pair, circle the most appropriate statement in the Rate Conclusion column. First Reaction Second Reaction Rate Conclusion (a) H 3 C N(CH 3 ) 2 O NaOH CH 3 OH H 3 C OCH 3 O NaOH CH 3 OH First reaction faster Second reaction faster Rates about equal Cannot tell in this case (b) H 3 C OCH 3 O NaOH CH 3 OH H 3 C OCH 3 O H 2 O CH 3 OH First reaction faster Second reaction faster Rates about equal Cannot tell in this case (c) H 3 C OCH 3 O NH 3 CH 3 OH H 3 C OPh O NH 3 CH 3 OH First reaction faster
