Question

Acetamide and ethylamine can be distinguished by reacting with

• A. aq. HCI and heat
• B. aq. NaOH and heat
• C. acidified $KMn0_4$
• D. bromine water

Answer 1

Answer: (B)

aq. NaOH and heat

Answer 2

When acetamide is heated with a NaOH it forms $NH_3$ gas but ethylamine cannot form $NH_3$. $CH_3 CONH_2 + H_2 O \xrightarrow {NaOH} CH_3 COONa + NH_3$ $CH_3 CH_2 NH_2 + H_2 O \xrightarrow {NaOH}$ No reaction
