Super Trick to Find Aldol Condensation Product in 20 seconds

WebAn aldol reaction involves the condensation of two carbonyl compounds to form a ß-hydroxyaldehyde or ß-hydroxyketone, the aldol product. The typical aldol reaction involves self condensation of the reactant ketone or aldehyde wherein one molecule adds to the other of the same type. An example of a self-condensation aldol reaction is shown in ... WebAldol products can be formed through either acidic or basic conditions and since they are usually exothermic the reaction will be driven to completion.
