Amines, like ammonia, can be protonated giving rise to alkylammonium ions. An example is the ethylammonium ion, CH3CH2NH3+, which is the conjugate acid of ethylamine. Amines are basic and form the largest and most significant class of organic bases.
24.8. HETEROCYCLIC COMPOUNDS
Incorporation of an oxygen, a nitrogen, a sulfur, or an atom of a related elementinto an
organic ring structure in place of a carbon atom gives rise to a heterocyclic compound. Since the
heterocyclic atom must form more thanone bond in order to be incorporated into a ring structure,
halogens do not form heterocyclic compounds although they may be substituents on a heterocyclic
ring structure. Heterocyclic compounds, like polycyclic ring compounds, are usually known by
