Reaction of Ethanamide with Phosphorus Pentoxide:
When ethanamide reacts with phosphorus pentoxide (P2O5), it undergoes dehydration to form acetonitrile (CH3CN) as the product.
Explanation:
Ethanamide, also known as acetamide, has the molecular formula CH3CONH2. It is a primary amide, which means it has an amide functional group (-CONH2) attached to a primary carbon atom (CH3).
Phosphorus pentoxide is a powerful dehydrating agent that can remove water molecules from organic compounds. When ethanamide is heated with phosphorus pentoxide, it undergoes dehydration to form acetonitrile (CH3CN) as the product.
The reaction mechanism involves the removal of a water molecule from ethanamide to form an intermediate compound called N-methylformamide. This intermediate is then dehydrated again by phosphorus pentoxide to form acetonitrile.
The chemical equation for the reaction is:
CH3CONH2 + P2O5 → CH3CN + HPO3
In this equation, HPO3 is the byproduct of the reaction, which is a white solid.
Conclusion:
The correct product of the reaction between ethanamide and phosphorus pentoxide is acetonitrile (CH3CN). The reaction involves the dehydration of ethanamide by phosphorus pentoxide to form an intermediate compound called N-methylformamide, which is then dehydrated again to form acetonitrile.
