peroxides, and permanganates. Nitriles may polymerize in
the presence of metals and some metal compounds. They
are incompatible with acids; mixing nitriles with strong
oxidizing acids can lead to extremely violent reactions.
Nitriles are generally incompatible with other oxidizing
agents such as peroxides and epoxides. The combination of
bases and nitriles can produce hydrogen cyanide. Nitriles
are hydrolyzed in both aqueous acid and base to give car-
boxylic acids (or salts of carboxylic acids). These reactions
generate heat. Peroxides convert nitriles to amides. Nitriles
can react vigorously with reducing agents. Acetonitrile and
propionitrile are soluble in water, but nitriles higher than
propionitrile have low aqueous solubility. They are also
insoluble in aqueous acids
