    The goal of this experiment was to synthesize dibenzalacetone by aldol synthesis. The name ’Aldol synthesis’ was taken from the words ’aldehyde and alcohol’. This is because the product of this reaction contains both an aldehyde and alcohol. The carbon-carbon bond-forming reaction is referred to as aldol addition. An aldol condensation yields many species of products if the reactant is more than one. Therefore‚ the aldehyde has to react with itself to yield one product. Procedure: Followed according
