Cat OlsonTA: Dr. William BowieCHEM 2204Experiment F1: An Aldol Reaction: Trans-4-nitrochalconeObjective:The purpose of this experiment was to explore the Aldol condensation reaction,wherein a new carbon-carbon bond was created. An enolate was formed, and subsequently theenolate participated in nucleophilic addition with a carbonyl carbon on the 4-nitrobenzaldehyde.The overall reaction was base-catalyzed by NaOH. The reaction’s final product was an α,β-unsaturated ketone, otherwise known as a chalcone. Hirsch filtration, melting point analysis, andIR analysis were all used in this experiment.Experimental Procedure:The procedure was followed as described in Mayo’s manual on pages509-516, along with the modifications provided in the Canvas documentAldol Modifications.Reaction Scheme:Data and ResultsData and Results TableAcetophenoneEthanol(95%)4-nitrobenzaldehydeNaOH(aqueous 10%)Trans-4-nitrochalconeFormulaC8H8OC2H5OH(pure)C7H5NO3NaOH (pure)C15H11NO3Molecular Weight120.16151.12253.25Amount (mg)106178147Amount (
