If a student is starting with diethylmalonate then the base they would use to generate the enolate would be NaOMe NaOEt NaOH None of the above. The synthesis of dibenzalacetone is an example of Dieckmann condensation Aldol condensation Michael reaction None of the above. Starting with a 1,6 - diester and treating it with NaOEt would be an example of  Aldol Condensation Claisen Condensation

please help me with both parts of this question, I am  very confused and am trying to study

The protocol says that, after adding in all the reactants, stir for an additional 15 minutes.  A student swirled for only 8 minutes and then, correctly, stopped and proceeded with isolating the product.  What did the student do that gave such confidence and accuracy? what could the student have done to confirm that he is ready to isolate the product? (another way to phrase the question)   the reaction is an aldol condensation reaction

providing the chemical structure of the missing reactants or the products.
