Show the starting material for each of the following reactions: O O O 3 Zn Br Br Br 2 CCl 4 The carbons with the carbonyl groups were formerly doubly bound to each other Careful, since Br 2 adds anti, sterochemistry is important rotate Br Br 4. Draw the organic product for this acid base reaction between propyne and sodium amide (a very powerful base). H H 3 C + NaNH 2 H 3 C...
