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...
