Question

Which of the following statements about the Aldol reaction is correct. Select all that apply. The aldol condensation reaction requires only a catalytic amount of base to form the a, -unsaturated carbonyl product In an Aldol reaction, the enolate is the electrophile that reacts with a neutral carbonyl nucleophile. Reacting 1 equivalent of LDA (lithium diisopropylamide) with 3-pentanone, the enolate will be formed quantitatively. Two equivalents of a ketone can be reacted with NaOH to form a B-hydroxycarbonyl product. Aldol reactions are used to create carbon-carbon bonds.

Answer 1

are which of the following statement about the Aldal reaction is Carrect, Answer, No, because aldal condensation reaction can be catalysed by both Acid and bars. No, m aldal reaction the reaction invalive ang aldehyde enalare reacting with anather malenele og aldehyde But, enalates are good Mucheophile and carbongle are good electrophiles. LDA is a strong bare, And LDA will quantitate -vely form enalate for example, 3-pentanone were react with LDA THE at -78° enclate anion Forms as major product and i high yield. gt bare as naon added to kelone, kelene are good neuchophile Chetone enolates but the oldal rachion kelones is nat particularly successful The mechanism intramale cellar aldal g reaction invalues formation aga kay enalate intermediate.
