preparation of dibenzalacetone by using an aldol condensation. full mechanism explained full detail
Full mechanism of reaction needed: A double crossed aldol condensation reaction will be carried out. The reaction uses the simple starting materials, acetone and benzaldehyde, to form the 17-carbon product known as dibenzalacetone.

Postlab Assignment for Minilab 34 “Preparation of Aldol Condensation Products” 1. Explain why benzaldehyde is expected to be the most reactive aldehyde among the three aldehydes used in this experiment. (used benzaldehyde, 4-methylbenzaldehyde, and 4-methoxybenzaldehyde) 2. What is the role of aqueous NaOH used in the experiment you carried out? 3. How would you change the procedures in this experiment if you wished to synthesize benzalacetophenone (C6H5CH=CHCOC6H5). Just indicate the two main organic starting materials. 4. Write a mechanism for...
