- What 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.
