15.5: Aromatic Heterocycles - Pyridine and Pyrrole
Pyrrole. Pyrrole is a five-membered heterocyclic ring which has 5 p orbitals and six pi electrons contributing to its aromaticity. Each carbon in pyrrole contributes one p orbital and pi electron. The nitrogen in pyrrole contributes two pi electrons by becoming sp 2 hybridized and placing its lone pair electrons into a p orbital. The ...
Pyrrole - an overview | ScienceDirect Topics
Pyrrole is very much less basic than secondary amines but much more acidic. Pyrrole is, however, still a very weak acid (p K a = 17.5). The nitrogen-bound proton can be abstracted from pyrrole by the use of strong bases such as sodium amide …
