Why only ethers are used as a catalyst in grignard reagent reactions?

Ethers are used as solvent in Grignard reaction and not as catalyst. This is because if we use other solvents which have acidic hydrogen, Grignard reagent will decompose and the Grignard reaction will not proceed further.

Why you use anhydrous ether during the preparation of Grignard's reagent why not anhydrous hexane?
You should really use anhydrous hexane; however, ethers can absorb large quantities of water; THF is completely miscible with water and will thus require extensive drying in order to get an anhydrous environment. Hexane absorbs very little water due to the unfavourable interactions between it and water. Therefore "non-anhydrous" hexane contains such a small quantity of water that the Grignard reagent formed will more than adequately dry the hexane.
Are alcohols more reactive than ethers?
No, ethers are generally less reactive than alcohols. Alcohols have a hydroxyl group (-OH) that can participate in various chemical reactions such as oxidation, dehydration, and nucleophilic substitution. Ethers, on the other hand, lack such a reactive functional group and are generally more inert.
What is the difference between the solvent properties of ethers and alcohols?
Ethers are hydrogen bond acceptors, but not hydrogen bond donors, as are alcohols. Ethers are generally unreactive as solvents, for that reason. Because of the polarity of the O-H bond in alcohol, the hydrogen atom comes on and off readily, allowing alcohol to act as a solvent in many reactions.
Why lah reactions can be done in ethers only why not in other solvents?
Solubility. LAH is not soluble in other solvents which would otherwise be appropriate.
Does ethers contain oxygen?
By definition, ethers must contain at least one oxygen atom.

Application of crown ethers in extraction of alkali and alkaline earth metals?
due to its behaviours of complexes crown ethers they act as strong phase transfer catalyst.
Do carboxylic acids or alpha-hydroxy ethers also give tollen 's reagent test?
yes...

When was Breaking the Ethers created?
Breaking the Ethers was created on 1997-03-01.
Is a thioether considered an ether?
Though they are very similar to ethers, they are not ethers. They're sulfides.
Does ethers contain oxygen?
By definition, ethers must contain at least one oxygen atom.
Are ethers aromatic?
Wow! are they!?!?!?!?
Do ethers contain oxygen?
yes
