The Grignard reaction must be run under an inert atmosphere, free of moisture because:

A. It prevents the formation of unwanted side products.
B. It enhances the reactivity of the Grignard reagent.
C. It allows for higher reaction temperatures.
D. It increases the yield of the desired product.

Answer :

Final answer:

In the Grignard reaction, an inert atmosphere free of moisture is necessary to prevent the formation of unwanted side products and increase the yield of the desired product.

Explanation:

The Grignard reaction must be run under an inert atmosphere, free of moisture because it prevents the formation of unwanted side products and increases the yield of the desired product. Moisture can react with the Grignard reagent and produce unwanted byproducts, reducing the yield of the desired product. In addition, moisture can also react with the Grignard reagent and consume it, reducing its reactivity. Therefore, it is important to ensure an inert and dry environment for the Grignard reaction.
