$CH_3NHCHO$

Vedclass · Answer

(D) In $CH_3NHCHO$,the lone pair of electrons on the nitrogen atom is involved in resonance with the adjacent carbonyl group $(C=O)$.This delocalization significantly reduces the availability of the lone pair for protonation.Although the $-NO_2$ group in $O_2NCH_2NH_2$ exerts a strong $-I$ effect,the resonance effect in the amide $(CH_3NHCHO)$ is more effective in reducing the basicity of the nitrogen atom.Therefore,$CH_3NHCHO$ is the weakest base among the given options.
