Reagents for aldol condensation

WebIn an aldol condensation, two molecules of aldehyde or ketone are joined together along with the loss of water. For example, in the aldol condensation shown in figure 1, two … WebThe reason for this formation is because the Aldol product is not usually isolated seen. The formation of an α, β unsaturated ketone is done through an elimination reaction (1). As seen in figure 4, a good elimination solvent is used to take the hydrogen (2). In this experiment, the specific aldol condensation done is mixed.
