Show Answer
Solution:
- (b) Acetamide and ethylamine can be distinguished by heating with $NaOH$ solution.
Acetamide evolves $NH_3$ but ethylamine does not.
$ \begin{aligned} CH_3 CONH_2+NaOH \xrightarrow{\Delta} \\ CH_3 COONa+NH_3 \\ CH_3 CH_2 NH_2+NaOH \longrightarrow \text{ No reaction. } \end{aligned} $
