Question

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

Answer 1

Hint:
We know that the Grignard reagent is generally used in organic chemistry. The organic chemical compounds are those compounds that consist of the carbon hydrogen bond in it. When one valence of specific carbon is free then this compound is named as alkyl group.

Complete step by step solution
As we all know, the Grignard reagent consists of the alkyl group, magnesium, and halides. Usually, they are organomagnesium halides. The general form of Grignard reagent is ${\rm{R - Mg - X}}$, where R is the alkyl group, Mg is magnesium, and X is halides they are chlorine, fluorine, iodine, bromine, and astatine.

The Grignard reagent reacts or combines with water quicker than any other aqueous solvent, which generally leads to the formation of alkanes. In this type of reaction, the nucleophile attack directs on one of the hydrogen, which is present in water. Then the magnesium of Grignard reagent in the solution will react with remaining hydroxide ions of water and forms magnesium hydroxide.

The ether is utilized as an alternative to water because generally, the Grignard reagent will not similarly combine with ether as it will combine with the water.

Note:
Commonly, the Grignard reagent ${\rm{R - Mg - X}}$ is used for the synthesis of many organic chemical compounds. It is used to make alcohol, esters, ketones, aldehydes, ethers and many more. It is used as a laboratory reagent in organic laboratory.
