2. (4 pts) Using the curved arrows, provide a reasonable mechanism for the following reactions. Br Н Br2 Нзс Нзс Br Нас Br Br2 Н-о Hас Но Н I
4. Short Answers (28 pts). A. (8 pts, 2 pts each) Classify each of the reactions below as stereospecific (A), only stereoselective (B), not stereoselective (C). Write the appropriate letter in the boxes next to each reaction. Only one letter should be written in each box. Only the actual products isolated in each reaction is shown. In other words, if a product isn't drawn, it isn't obtained by that reaction. сна HC-Br Nal, acetone CH3 CLH CH3 NaOCH2CH3 |нс CH3...
