Please answer the following questions/fill in the data tables based on the following experiment. EXPERIMENTAL PROCEDURE: Place sodium hydroxide (2.500 g) in a 100 mL Erlenmeyer flask and add water (25.0 mL) and ethanol (20.0 mL). Add a magnetic stirrer bar and stir until all the NaOH has dissolved. To a second reaction vessel, add benzaldehyde (2.650 g, 0.025 mol) and acetone (0.725 g, 0.0125 mol). Add approximately half of the aldehyde-ketone solution to the sodium hydroxide solution, and stir...

what is the theoretical yield of anisalacetophenone and
dibenzalacetone formed? thank you.
The Aldol Condensation Precautions: Acetone, ethanol and acetophenone are flammable; work in a fume hood. Sodium hydroxide is a strong base and can cause severe skin burns and eye damage. Safety goggles are required. Gloves are recommended. Purpose To carry out two Aldol condensation reactions in which no heat is needed to obtain the condensation product. The two reactions differ in the number of enolizable protons at the...
