Imidazole - Wikipedia
Some resonance structures of imidazole are shown below: Amphoterism. Imidazole is amphoteric, which is to say that it can function both as an acid and as a base. As an acid, the p Ka of imidazole is 14.5, making it less acidic than carboxylic acids, phenols, and imides, but slightly more acidic than alcohols.

2009年9月1日 · Some resonance structures of imidazole are shown below: Imidiazole is amphoteric, i.e. it can function as both an acid and as a base. As an acid, the p Ka of imidazole is 14.5, making it less acidic than carboxylic acids, phenols, and imides, but slightly more acidic than alcohols. The acidic proton is located on N-1.
Imidazole (Im) itself is an aromatic five-membered aromatic heterocy-cle with two nitrogen atoms. This molecule is a basic build-ing block of many biologically important molecules, e.g., histamine and histidine. The imidazole units in the com-plexes we consider ( Im2H+ and Im3H+ ) are held together by N − H ...
