QUATERNARY AMONIUM BASE
1-hydroxi, 2-methyl- propane
Methyl-amine
Dimethyl-amine
Trimethyl-amine
PYRIDINE
PYRIDAZINE
PYRIMIDINE
PYRAZINE
The lone pair of the N is less prominent than in amines
WHY?
because the aromatic system steals an electron from the nitrogen. Very weak bases.
PYRROLE
IMIDAZOLE
ANILINE
Describe aryl-amines (lone pair, NH bonds)
The lone pair of the N is partially lost, because it tends to conjugate with the aromatic system.
The N-H bonds are more polarized due to the partially lost lone pair.

1 - amines
2 - esters
3 - acid anhydrides

-> ESTER OF CARBAMIC ACID
A CARBAMATE
UREA, CARBAMIDE:

Imine
Is imine a strong base?
Yes
