CH3CH2NH2 contains a basic NH2 group, but CH3CONH2 does not, because;

1. Acetamide is amphoteric in nature

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
