Please help answer P1-P4 for this Perkin Reaction Lab Perkin Reaction Organic REActivity PERKIN REACTION (ALDOL CONDENSATION) The Reaction Scheme: Formation of trans-cinnamic acid The following reaction is named the Perkin Reaction. It is a very specific type of Aldol condensation that forms a variety of cinnamic acid derivatives. In this lab, you will perform a Perkin reaction using benzaldehyde and potassium carbonate in acetic anhydride to form trans- cinnamic acid (1). Trans-cinnamic acid is a natural compound found in...
How many moles of benzaldehyde (density d = 1.04 g/ml), (molecular weight mw = 106.12 g/mol) are required to react with 1.0 ml of acetone: (density d = 0.79 g/ml), (molecular weight mw = 58.08 g/mol)? 6. What is approximate theoretical yield for problem # 5 if you obtained 2.1 grams of dibenzylidene acetone (mw = 234.29 g/mol)?
