Answer:
Pyridine
Explanation:
Pyridine is a stronger nucleophile than pyrole ,
Since , both have a lone pair of electron on its nitrogen atom , and both the structure are aromatic in nature .
But , in case of pyrole , the lone pair on nitrogen participates in the delocalization and makes the ring aromatic in nature . hence the lone pair losses its nuleophilic character .
But , in case of pyridine , the lone are free to act as a nucleophile , since they are not involved in the delocalization of the ring .
