Both pyridine and pyrrole are nitrogen containing aromatic heterocyclic compounds. When treated with HCl, only pyridine forms a hydrochloride salt, whereas pyrrole is unreactive. Which of the following is not a valid explanation for this observed reactivity?



◦ The lone pair on pyridine can be protonated without disrupting the aromatic stability.
◦ The lone pair on pyrrole is involved in making the compound aromatic and thus is less susceptible to protonation.
◦ The lone pair on pyridine is not part of the aromatic system.
◦ The lone pair on pyrrole is sp3 hybridized and is less prone to protonation.
◦ Protonation of pyrrole leads to a nonaromatic cation, which is less stable.
