Preferred Label : carbonium ion;
IUPAC definition : the term should be used with great care since several incompatible meanings are currently
in use. it is not acceptable as the root for systematic nomenclature for carbocations.in
most of the existing literature the term is used in its traditional sense for what
is here defined as carbenium ion.a carbocation, real or hypothetical, that contains
at least one five-coordinate carbon atom. a carbocation, real or hypothetical, whose
structure cannot adequately be described by two-electron two-centre bonds only. (the
structure may involve carbon atoms with a coordination number greater than five.);
