1226 CHAPTER 25 • THE CHEMISTRY OF THE AROMATIC HETEROCYCLES B. Acidity of Pyrrole and Indole Pyrrole and indole are weak acids. With p K a values of about 17.5, pyrrole and indole are about as acidic as alcohols and about 15–17 pK a units more acidic than primary and secondary amines (Sec. 23.5D). The greater acidity of pyrroles and indoles is a consequence of the resonance stabilization ...
