Question

1. The dibenzalacetone preparation reaction is almost all reversible. However, good product performance is easily obtained. Explain. 2. State why the reaction between acetone and 2-pentanone would not be a good method for preparing 4-methyl-3-hepten-2-one. 3. Write down the reaction of the congestion of benzaldehyde with acetophenone. 4. Suggest a way to modify the procedure used in the laboratory so that the reaction produces benzalacetone instead of dibenzalacetone

Answer 1

Naon - Benzaldehyde acetone acetone. Dibenzalacetone. → This above reaction is a All the cross-aldo reaction are the steps in This above reaction is cross-aldo reaction. reversible, but where removal of water takes place from the aldo : (also known as condensation) make this reaction meversille or shift the reaction forward direction, reaction is on removal of water we carbonyl conjugated with alkene (double bow this gives stabligation in the molecule. Cnolate on heaters LA chat na cross-aldo product one more tinre to give game reaction takes place dibenzalacetone. Sorry!! But we are supposed to do only first question If multiple questions are posted. Itan But I can help you for 2nd question in short. and gxh is cross-aldo reaction but it's not good for od product from the given reactant because we poft will get the multiple products product from also preparation of
