Please match the products to each reaction. Which reagent will complete the following reaction? Consider this scheme. Which species could be used to reverse the formation of cyanohydrin? A H3?O+ B NaCN C water D Benzaldehyde Consider this scheme. Why does a ring form with a single ethylene glycol on A rather than two molecules of ethylene glycol to form acyclic acetals? A Intramolecular reactions are unfavorable when compared to intermolecular reactions B Acyclic molecules are unfavorable compared to rings in all cases C The change in entropy is favorable for ring formation and strain is low in a five- membered ring D Sterics prevents acyclic molecules from forming in this case
