Question

Among the following the weakest base is (A) C6H5CH2NH2 (B) C6H5CH2NHCH3 (C) O2NCH2NH2 (D) CH3NHCHO

Tardigrade Admin · Accepted Answer

The weakest base is CH3NHCHO The lone pair of electrons cannot be easily donated to suitable Lewis acid as the nitro group is electron-withdrawing group. As amides are not basic in nature and given option (D) is amide structure and other compounds are amines.
