Usage And Synthesis
chemical properties

Imidazole is between the two nitrogen atoms of five membered heterocyclic compounds containing. The unshared electron pair of 1-bit nitrogen atom in imidazole ring participates in the cyclic conjugation, reduces the electron density of the nitrogen atom, and makes hydrogen of the nitrogen atom easily leave in the form of hydrogen. Therefore imidazole has weak acidity, and can form salt with strong base.
The unshared electron pair of 3-bit nitrogen atom in imidazole ring doesn't participates in the cyclic conjugation, while it occupies the sp2 hybridized orbital, can accept protons, and form salt with strong acid. Alkaline of imidazole is slightly stronger than pyrazole and pyridinee.
There is tautomerism in the imidazole ring. The hydrogen on the 1-bit nitrogen atom can be transferred to the 3-atom, therefore, imidazole derivatives with same substituent respectively on 4-bit and 5-bit are tautomers.
