Vedclass · Answer

(B) The basicity of amines depends on the availability of the lone pair of electrons on the nitrogen atom.$(A)$ $N$-ethylaniline: The lone pair on the nitrogen atom is in conjugation with the benzene ring,which decreases its availability for protonation.$(B)$ $N$-ethylbenzylamine: The nitrogen atom is attached to a $CH_2$ group (benzyl group),so the lone pair is not in conjugation with the benzene ring. It is a secondary aliphatic amine,which is more basic than aromatic amines.$(C)$ $N$-ethylbenzamide: The lone pair on the nitrogen atom is involved in resonance with the carbonyl group $(C=O)$,making it significantly less basic.Therefore,$N$-ethylbenzylamine $(B)$ is the most basic compound.
