Are secondary amines more basic than primary?
In general, secondary amines are more basic than primary amines, which are more basic than tertiary amines. Amines are capable of forming hydrogen bonds with water and therefore have strong intermolecular forces that result in higher melting points, boiling points, and water solubility.
Is pyridine a tertiary amine?
Pyridine is a basic amine, and reacts, like other tertiary amines, with alkyl halides to form quaternary ammonium salts.
Which amine is the weakest base?
Comparing the other two to ammonia, you will see that methylamine is a stronger base, whereas phenylamine is very much weaker. Methylamine is typical of aliphatic primary amines – where the -NH2 group is attached to a carbon chain.

CH3N(CH3)2 and N(CH3)3 are tertiary amines tertiary amines have no hydrogen atom and three alkyl or aryl groups attached to the nitrogen.
