Vedclass · Answer

(D) The basicity of amines depends on the availability of the lone pair of electrons on the nitrogen atom for protonation.$1$. In $p-$Nitroaniline,the $-NO_2$ group is a strong electron-withdrawing group ($-I$ and $-M$ effect),which decreases the electron density on the nitrogen atom,making it the least basic.$2$. In Acetanilide,the lone pair on the nitrogen atom is involved in resonance with the carbonyl group $(C=O)$,making it much less basic.$3$. In Aniline,the lone pair on the nitrogen atom is involved in resonance with the benzene ring,reducing its availability for protonation.$4$. In Benzylamine $(C_6H_5CH_2NH_2)$,the nitrogen atom is attached to a $CH_2$ group,which is not directly attached to the benzene ring. Therefore,the lone pair is not involved in resonance with the ring,making it the most basic among the given options.
