Question

Why is water not used as solvent synthesis of Grignard reagent?

Open in App

Solution

Grignard reagent reacts with water faster than any other solvent which leads to the formation of alkanes. In this reaction, the nucleophile attack on one of hydrogen of water. Then magnesium in the solution will react with remaining OH ions which gives magnesium hydroxide.

Ether is used instead of water because Grignard reagent will not react with ether in the same way as it will react with water.
