The aldol reaction

An aldol condensation is a condensation reaction in organic chemistry in which two carbonyl moieties (of aldehydes or ketones) react to form a β-hydroxyaldehyde or β-hydroxyketone (an aldol reaction), and this is then followed by dehydration to give a conjugated enone. The overall reaction is as follows (where the Rs can be H): WebThis is known as the aldol condensation reaction the net result of the reaction is adding two molecules together and removing water. And this particular reaction will occur even at room temperate because the …
