Question
Among the following amines, the strongest Bronsted base is $..........$
✓

Answer

Aniline is weaker base than $NH_3$ due to delocalization of lone pair of electrons on the $N-$atom into the benzene ring. Pyrrole $(c)$ is not at all basic because the lone pair of electrons on $N-$atom is donated towards aromatic sextet formation. Therefore, pyrrolidine $(d)$ has a strong tendency to accept a proton and is hence, the strongest base.
