- Which statement describes why aldol reactions with ketones are low yielding? A.Ketones do not have acidic protons. B.Ketones are too electron poor at the carbonyl carbon. C.Ketones can attack other ketones well but perform poorly in self-condensations. D.The product of a ketone addition to a ketone has considerable steric strain.arrow_forwardIn an aldol condensation reaction, acetone and benzaldehyde are mixed in the presence of sodium hydroxide to produce dibenzalacetone. Does it matter whether the acetone is added first to the aq. NaOH solution then the benzaldehyde, or if the benzaldehyde is added first to the aq. NaOH solution, then the acetone?
