Cations
HR3N+
formed by hydronation of an amine
R3N
. 'Non-quaternary ammonium ions' is a synonymous term, e.g. prolinium,
PhN+HMe2
, N,N-dimethylanilinium.
Note:
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 @H02904@ with a hydrocarbyl group. Aminium ions form an exception, made possible by the availability of the class name ammonium ions.
