Lab : Aldol Condensation Purpose. In this lab you will conduct the Aldol condensation reaction under solid-state reaction conditions that will involve grinding reactants in the solid phase. You must read ahead and learn about this reaction and the chemical mechanism for the Aldol condensation. There are two possible products which are the initial Aldol or subsequent elimination product. You will need to isolate and purify your reaction product. You will use your melting point, IR, 1H and 13C NMR spectra to...

In Organic Chem II from the Aldol Condensation lab (using 3-nitrobenzaldehyde, acetophenone, ethanol, sodium hydroxide, methanol and final product 3-nitrochalcone) please help anser the following answer. Please write clear; many times it's hard to read response on Chegg-thank you. 1. There are two possible products of this aldol condensation. Draw the structure of both. 2. Explain why only one aldol product is formed in this reaction. Comment on both the reactivity of the starting materials as well as your experimental...

Organic Chemistry 2
Experimental Outline In its simplest form, the aldol condensation is a self-addition involving two molecules of the same aldehyde or ketone, in the presence of a base, and results in the formation of a new carbon-carbon bond joining the carbonyl carbon of one molecule to the a-position of the second. In many cases - if the reaction conditions aren't sufficiently mild - the initially formed aldol product reacts further in an elimination reaction to give what is...

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...

8. The Aldol condensation reaction can be used to synthesize an ingredient commonly found in commercially available sunscreens. The procedure for this reaction is given below. Benzaldehyde (3.0 mL) and acetone (1.0 mL) are combined in a 25.0 mL round bottom flask. 2.5 M NaOH(aq) (1.4 mL) was then added, and the reaction was stirred for 30 minutes at room temperature. The resulting precipitate was isolated, and recrystallized using ethanol. The isolated yield of the target product was 2.68 g,...
