Vedclass · Answer

(D) To determine the strongest Bronsted base,we look for the availability of the lone pair on the nitrogen atom.$1$. In Aniline $(C_6H_5NH_2)$,the lone pair on $N$ is delocalized into the benzene ring due to resonance,making it less available for protonation.$2$. In Ammonia $(NH_3)$,the lone pair is localized but lacks the electron-donating alkyl groups that increase basicity.$3$. In Pyrrole $(C_4H_4NH)$,the lone pair on $N$ is part of the aromatic sextet (delocalized),making it non-basic.$4$. In Pyrrolidine $(C_4H_8NH)$,the lone pair is localized on the nitrogen atom and is not involved in resonance. Additionally,the alkyl chain provides an inductive effect ($+I$ effect) that increases the electron density on the nitrogen,making it the most basic among the given options.
