Reaction:
When benzamide is treated with POCl3, it undergoes the Vilsmeier-Haack reaction to form benzonitrile.
Explanation:
1. Vilsmeier-Haack Reaction:
- The Vilsmeier-Haack reaction involves the conversion of an amide group into a nitrile group using POCl3.
- In this reaction, POCl3 acts as a dehydrating agent and reacts with the amide functional group to form an iminium ion intermediate.
- The iminium ion then undergoes hydrolysis to yield the nitrile product.
2. Formation of Benzonitrile:
- In the case of benzamide, the reaction with POCl3 leads to the formation of benzonitrile.
- The amide group in benzamide is converted into a nitrile group during the Vilsmeier-Haack reaction, resulting in the formation of benzonitrile as the product.
Therefore, the correct product formed when benzamide is treated with POCl3 is benzonitrile.
