WebStep 1: An acid/base reaction. Since we only have a weak nucleophile so activate the nitrile, protonation makes it more electrophilic. Step 2: The water O functions as the nucleophile attacking the electrophilic C in the C≡N, with the electrons moving towards the positive center. Step 3: An acid/base reaction. WebWhen nitriles are hydrolysed you can think of them reacting with water in two stages - first to produce an amide, and then the ammonium salt of a carboxylic acid. For example, ethanenitrile would end up as ammonium ethanoate going via ethanamide. In practice, the reaction between nitriles and water would be so slow as to be completely ...
