Vedclass · Answer

(B) The basic nature of an amine is due to the presence of a lone pair of electrons on the nitrogen atom,which is available for bond formation with a Lewis acid.In $CH_3NH_2$,the $+I$ effect of the $-CH_3$ group increases the electron density on the nitrogen atom,making it more available for donation compared to $NH_3$.In $C_6H_5NH_2$,the lone pair is involved in resonance with the benzene ring,reducing its availability.In $CH_3CONH_2$,the lone pair is involved in resonance with the carbonyl group $(C=O)$,significantly reducing its basicity.Therefore,$CH_3NH_2$ is the strongest base among the given options.
