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” anywhere on this exam where appropriate. 1. (4) Hydroboration-oxidation is an addition reaction that is (circle one from each set): (a) Syn Anti A mixture of syn and anti Not syn or anti (b) Markovnikov Anti-Markovnikov A Markovnikov/anti-Markovnikov mixture None of these choices 2. (3) Write an example of the hydroboration-oxidation reaction that clearly illustrates your choices from the previous question. Include all reactants and products, but do not include any mechanism details. Questions 3–5 refer to the proposed reaction of molecule A with Br 2 and h ν to give molecules B and C : Molecule A Molecule B Molecule C 3.
