1If impurities are present in your crude sample, the melting point rangefor your product will be lower than the range of pure (E)-4-(3-(4chlorophenyl)-3-oxoprop-1-en-1-yl)phenyl benzoate . Also, yourmelting point range may be greater than 2 degrees. According to theliterature reviews the melting point of pure (E)-4-(3-(4-chlorophenyl)-3oxoprop-1-en-1-yl)phenyl benzoate is 131-133 oC but we recorded themelting point of this product isFirst Drop at: 128.4 degree CelsiusMelting Point at: 133.2 degree CelsiusSo the range of melting point is aprox (5oc) which indicates there issome impurities/ by products present in the final product.But melting point is approximately matching with standard reportedmelting point. Which indicates very little by products are present?Also by GCM it has been confirmed that the final reaction productcontain 98.165% of compound 1 ((E)-4-(3-(4-chlorophenyl)-3-oxoprop1-en-1-yl) phenyl benzoate) and 1.835% of other by product.2 Synthesis of chalcone This method which we adopt is standard andeffective method for synthesis of chalcone but workup and purificationof compound need to be improved.1) We should use the thin layer chromatography (TLC) formonitoring of reaction so that we can find out the how muchreactant is present in the reaction mixture and approx how muchtime it will take to complete the reaction as well as it will tell howmany products formed.2) Since chalcone is soluble in ethanol because it is polar organicsolv
