and other nitrogen compounds are the bases of the organic world.
The amines are prepared by reacting chlorides of hydrocarbons with
ammonia with a hydrocarbon group:
Amines are classified as primary, secondary or tertiary, according
to the number of nonhydrogen substituents they have on the nitrogen.
Tetraethylammonium ion is a quarternary ammonium ion, but there
obviously can be no quarternary amine molecules. All of these amines
can add a proton to form a substituted ammonium ion, and all are
about as strong bases as ammonia, with 10.
The secondary and tertiary amines are toxic, with a nauseating fishy
