Aldol Condensation Reaction
Please actually explain instead of showing a mechanism. I do know the mechanism but am having a hard time understanding why these two other reactions are not favored.

2. Why does the mixed aldol condensation, producing benzalacetophenone is the main reaction in this experiment and NOT both other possible reactions; acetophenone condensation and Cannizzaro benzaladehyde reaction? 3. Propose a reason to explain the statement that the trans-benzalacctophenone isomer is the major product in aldol condensation 4, Explain why the main product from the bromine addition to the trans-acetophenone is crythro-dibromide 5.

In our Aldol condensation reaction, p-anisaldehyde and acetophenone were reacted in the presence of NaOH to form trans-p-anisalacetophenone. Provide a benchtop test that can enable a student to confirm that the correct product was obtained at the end of an aldol condensation experiment, and explain how the test will work.

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...

1. The aldol condensation reaction belongs to a group of reactions characterized by formation of an enolate. For each of the following aldehydes or ketones, draw the enolate ion that forms when treated with a strong base such as sodium hydroxide. If an enolate cannot form, put NR (no reaction). 2. The first step in the aldol addition of acetaldehyde is an acid base reaction (proton transfer). pka = 16 pka = 15 OH a. The pk, for each acid...
