Which of the following compounds is the most basic in an aqueous medium? — Amines Chemistry Question

💡 Solution & Explanation

Acetanilide, Aniline, and p-Nitroaniline all feature a nitrogen atom whose lone pair is depleted by resonance. Benzylamine ($C_6H_5CH_2NH_2$) possesses an $sp^3$ hybridized methylene group insulating the amine from the ring, blocking resonance and making it the strongest base.
