Chemistry 14D Winter 2009 Final Exam Part A Page 1 For any question on Part A or Part B 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. You may use “Ph” and “Ar” anywhere on this exam where appropriate. 1. (15) Complete each reaction by writing the reactant(s) or major product in the boxes. If more than one product is formed write only the major product. If no reaction occurs write “NR.” Do not provide any mechanisms. (a) (b) (c) (d) (e) 2.
