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.

Aldol Condensation (multi-part question) 1. a. Why does mixing of solid 3,4-dimethoxybenzaldehyde and solid 1-indanone result a liquid solution? b. Why is the condensation (dehydrated) product rather than the aldol addition (hydrated) product obtained in this experiment? (What makes the condensation product exceptionally stable?) c. Why does the enolate ion of an aromatic ketone react faster with an aldehyde group (producing a crossed-aldol reaction) than with the carbonyl group of another molecule of ketone?

What is the expected mass of the product of the reaction of 0.0015 moles of 3,4-dimethoxybenzaldehyde and 0.0015 moles of 1-indanone with 0.05g of solid NaOH and addition of HCl solution afterwards? This is an aldol condensation (green chemistry) problem.
Aldol Condensation Reaction
Why is the major product between p-anisaldehyde and acetophenone the crossed aldol product rather than the Cannizzaro reaction or the self-condensation ofacetophenone?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.

In today's experiment you will synthesize the a,ß-unsaturated ketone from 3- nitrobenzaldehyde and acetophenone via an aldol condensation. Once the aldol product forms, the reaction spontaneously dehydrates to the conjugated enone. This reaction fulfills some of the principles of green chemistry in that it has high atom economy, produces water as the only major byproduct, and uses ethanol as a non-toxic solvent. ON NaOH Etон Ph Which aldehyde will work better in this reaction as an electrophile: 4-cyanobenzaldehyde or 4-methoxybenzaldehyde?...

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...
