Web1226 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 …

WebMar 2, 2024 · That said, every resonating structure (except the uncharged one) for pyrrole and furan will create a formal positive charge on the hetero-atom. Since N is less electronegative than O, it will be slightly more stable than O with that positive charge. Hence, pyrrole will be more aromatic than furan.
