Question

C2H5)3 N and C6H6 which is more basic and why?​

Answer 1

Methylamine is more basic than aniline. In aniline, ring structure delocalizes the electrons from individual atoms. The source of basicity of amine group is the lone pair on the Nitrogen atom. The lone pair is also delocalized in Aniline and resource structures are formed as the lone pair on Nitrogen is delocalized, it cannot donate an electron, therefore loses its basicity. Methylamine, CH3NH2, does not have resonance and thus it is more basic as the Nitrogen can donate electrons. Therefore Methylamine is more basic than Aniline.
