Explain, based on the corresponding ultraviolet spectra, why dibenzalacetone is found to be yellow, even though its starting reagents are colorless. Please indicate why the reaction between acetone and 2-pentanone would not be a good method of preparing 4-methyl-3-hepten-2-one. Write the reaction of the condensation of benzaldehyde with acetophenone. Suggest a way to modify the laboratory procedure so that the reaction produces benzalacetone instead of dibenzalacetone.
