Benzenamine

Vedclass · Answer

(C) The basicity of amines depends on the availability of the lone pair of electrons on the nitrogen atom for protonation.In $Phenylmethanamine$ $(C_6H_5CH_2NH_2)$,the lone pair is localized on the nitrogen atom as it is not in conjugation with the benzene ring.In $Benzenamine$ $(C_6H_5NH_2)$,$N$-Methylaniline,and $N, N$-Dimethylaniline,the lone pair on the nitrogen atom is involved in resonance with the benzene ring,which decreases its availability for protonation.Among the aromatic amines,the presence of electron-donating alkyl groups on the nitrogen atom increases the electron density on the nitrogen,making them stronger bases than $Benzenamine$.Therefore,$Benzenamine$ has the least available lone pair due to resonance and the absence of electron-donating groups,making it the weakest base among the given options.

Which among the following compounds is the weakest base?
