3. (4 pts) The key step involves a base pulling off one of the benzylic hydrogens in the starting material. Given that the pk of an alkane hydrogen is > 50 and the pk, of a benzylic hydrogen is < 40, explain why potassium hydroxide can be used instead of sodium amide to synthesize 1,2-diphenylethyne from a vicinal dibromide. 4. (4 pts) Fill in the following table showing amounts to use and theoretical yield. Show your work. Product 1,2-diphenylethyne Amounts...

Page 1 Synthesis using Carbonyl O-Substitution Chemistry Preamble This experiment involves the synthesis of target molecules using a-substitution chemistry. You are assigned two target molecules, one of which is best synthesized by an alkylation approach, while the other is best synthesized by an addition or condensation approach. You must do the following: 1. Perform a retrosynthetic analysis on the two target molecules assigned to you. In each case the organic starting material (what you have to work backwards toward) depends...
