Answer :
1. False.
2. True.
Reactions with Grignard reagents are typically carried out with ethers as solvents, but they can also be carried out with other organic solvents such as THF (tetrahydrofuran) or diethyl ether.
Water is generally not used as a solvent in Grignard reactions because it reacts with the Grignard reagent and can lead to the formation of unwanted byproducts.
Grignard reagents are organometallic compounds that contain a carbon-magnesium bond. They are highly reactive and are commonly used for the formation of new carbon-carbon bonds in organic synthesis. The choice of solvent in a Grignard reaction depends on several factors, including the reactivity of the Grignard reagent and the nature of the reaction.
Ethers such as diethyl ether and THF are often used as solvents because they are relatively inert and can dissolve both the Grignard reagent and the organic substrates involved in the reaction. Water, on the other hand, reacts with the Grignard reagent to generate magnesium hydroxide and the corresponding alkane, which can interfere with the desired reaction and decrease the yield of the desired product.
Therefore, water is generally avoided as a solvent in Grignard reactions, although there may be exceptions in specific cases.
