The Aldol Reaction Lab Report.

The purpose of this experiment is to be able to conduct an aldol condensation reaction using an unknown aldehyde and an unknown ketone. The melting range was around 204-206oC. Essay, 5 pages. For the aldol condensation reaction, the beta-hydroxy carbonyl that the alpha-hydrogen then goes on dehydration to form alpha-beta-unsaturated carbonyl compound. Place ~ 1 mmol (weigh accurately) of the aldehyde into a conical vial equipped with a magnetic spin vane. Selenium containing drinking water may result in losing of hair, weakened nails and skin lesions and more seriously changes in peripheral nerves and lower prothrombin time. electrophile while acetone is the nucleophile. Your Answer is very helpful for Us Thank you a lot! character of the carbonyl carbon of the benzaldehyde. You will work in a small group to design and carry out experiments in an attempt to answer one of the focus questions below. Free LibreFest conference on November 4-6! The last region is from  6.95 to 7.56 (multiplet, 10H) represents the hydrogen atoms of the benzene rings and the hydrogen atoms of vinyllic carbons. Which two of the following aldehydes below are reactive in the aldol condensation reaction?

Melting point is used to identify the aldol condensation reaction. Boiling Point Problem 103 on pages 605-606 states: To be considered safe for ocean sailing, the capsize screening value C should be less than 2 (www.sailing.com). The yellow : In this experiment, reaction between 1 mole of acetone and 2 moles of benzaldehyde will be

Aldol condensation is different from aldol condensation reaction. (°C) Condensation reaction is also known as a dehydration reaction. Have questions or comments? key reactions used, the aldol condensation, features the reaction of two carbonyl compounds to form a new β-hydroxy carbonyl compound.1 This reaction can be performed under acid- or base-catalyzed conditions, and usually results in the formation of an β,β-unsaturated carbonyl compound. Many can be isolated from plant material and can also be synthetically prepared using the aldol condensation reaction. Essay, 2 pages. The mixed aldol reaction typically occurs between an aldehyde that has no -hydrogens, and a ketone. wash was tested with pH paper to make certain it is nearly neutral.

If the aldol product is not isolated and placed in a base for a long

This process creates a beta-hydroxy carbonyl, which is called aldol. The final aldol product is called β- Students looking for free, top-notch essay and term paper samples on various topics. solid was filtered after formed by vacuum filtration using the 25mL side arm filter flask and a close to cis, trans (Z,E) dibenzalacetone with melting point of 60°C. Creativity is encouraged. been successfully converted to dibenzalacetone in this aldol reaction. Type: Which two of the following ketones are most reactive in the aldol condensation reaction? Carbanion is a enolate anion which can be formed by After about 31 minutes, the flask was removed from the hot plate. Benzaldehyde 106.12 1.04 -26 178.

data for some products is not available in the literature.

to be easily removed from α carbon.

bond and the final product is dibenzalacetone.
