2. Pyridine and pyrrole are both aromatic heterocyclic nitrogenous organic bases. However, they are not equally as strong as bases however. Pyridine is a much better base (pKb-8.75) than pyrrole (pKb 13.6. Provide an explanation for the difference in basicity between the two compounds. (12.5 points) Pyrrole Pyridine As a part of your answer, start by showing the mechanism of how each molecule accepts a proton.
