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 negligible.

WebHydrolysis of acetonitrile (the adding of water to its triple bond) is a useful synthetic procedure. Alkali metals such as sodium ( Na) and potassium ( K) attached to the cyanide group (carbon and nitrogen joined by three bonds, ‒C≡N or -CN for short) is deadly poisonous. One factor making it so poisonous is most inorganic cyanides ionize in water.
