Why lah reactions can be done in ethers only why not in other solvents?
Lah reactions, which involve the addition of an alkyl lithium compound to a carbonyl compound to form a new carbon-carbon bond, are typically conducted in ethers like diethyl ether because ethers can solvate the reactive lithium cation and allow for the reaction to proceed smoothly. Ethers are less acidic and less likely to react with the alkyl lithium reagent compared to other solvents such as alcohols, which can deactivate the alkyl lithium reagent by protonation.
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.
Does ethers contain oxygen?
By definition, ethers must contain at least one oxygen atom.
Why are Grignard reagents synthesized in an ether medium?
Grignard reagents are stable in ether medium. Ether generally forms an adduct with Grignard reagents. In addition, if solvents containing acidic hydrogens are present, Grignard reagents are decomposed to the corresponding hydrocarbon.

Do carboxylic acids or alpha-hydroxy ethers also give tollen 's reagent test?
No, carboxylic acids and alpha-hydroxy ethers do not give a positive Tollen's reagent test. Tollen's reagent is typically used to test for aldehydes and alpha-hydroxy ketones, which undergo oxidation to carboxylic acids in the presence of Tollen's reagent. Carboxylic acids and alpha-hydroxy ethers do not contain the specific functional groups that can undergo this reaction with Tollen's reagent.

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.

Are ethers least reactive?
Ethers are generally less reactive compared to other functional groups like alcohols or halides. However, they can be cleaved by strong acids or oxidizing agents, making them susceptible to certain reactions. Additionally, their reactivity can vary depending on the specific structure and environment.

When was Breaking the Ethers created?
Breaking the Ethers was created on 1997-03-01.
What are the properties and uses of t-butyl iodide?
T-butyl iodide is a chemical compound with the formula (CH3)3CI. It is a colorless liquid that is used as a reagent in organic synthesis, particularly in the preparation of t-butyl ethers and esters. T-butyl iodide is also used as a source of t-butyl radicals in radical reactions. It is highly reactive and should be handled with care due to its potential hazards.
Is a thioether considered an ether?
Though they are very similar to ethers, they are not ethers. They're sulfides.
