- 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_forwardWhat aldehyde or ketone is needed to prepare each compound by an aldol reaction?arrow_forwardDraw the aldol product formed from each compound.arrow_forward
- Aldol Condensation What products are formed? What is the difference between aldol reactions and aldol condensation? What type of reaction condentionas are used?arrow_forwardDraw the final product formed in the reaction below.arrow_forwardThe synthesis of carbohydrates can be particularly difficult because of the large number of chiral centers and OH functional groups present. Epoxides can be useful synthetic intermediates in carbohydrate syntheses. Draw the product of the following reaction of a Gilman reagent with each epoxidearrow_forward
