- Draw a mechanism for the following transformation. [H,SO4] cat. HO.arrow_forwardWhat is the major difference between the base-catalyzed and acid-catalyzed processes for nucleophilic addition of water to aldehydes and ketones? a. The base-catalyzed reaction takes place rapidly because hydroxide ion is a much better nucleophile than neutral water. b. The rate of reaction in base catalyzed process is slower than acid catalyzed process. c. The acid-catalyzed reaction takes place rapidly because the protonated carbonyl compound is a much better electrophile than the neutral compound. d. Only 1 and 3 are correct.arrow_forwardDraw the enol form of each keto tautomer in parts (a) and (b), and the keto form of each enol tautomer in parts (c) and (d).arrow_forward
