formed by hydronation of an amine
. 'Non-quaternary ammonium ions
' is a synonymous term, e.g. prolinium,
If a class X can be hydronated to Xium ions the class Xium ions commonly includes
the derivatives formed by the replacement of the added hydron
with a hydrocarbyl group. Aminium ions form an exception, made possible by the availability
of the class name ammonium ions.
