CH₃CH₂NH₂ contains a basic NH₂ group, but CH₃CONH₂ does not, because;
1. acetamide is amphoteric in character
2. in CH₃CH₂NH₂ the electron pair on N-atom is delocalized by resonance
3. in CH₃CH₂NH₂ there is no resonance, while in acetamide the lone pair of electron on N-atom is delocalized and therefore less available for protonation
4. none of the above
