Preparation of C5H11OH with grignard reagent?
To prepare C5H11OH using a Grignard reagent, you would typically start with an alkyl halide such as 1-bromopentane (C5H11Br) and react it with magnesium to form the Grignard reagent, in this case, a pentylmagnesium bromide. You would then add this Grignard reagent to a carbonyl compound like formaldehyde (HCHO) or acetone (CH3COCH3) to form the desired alcohol product through nucleophilic addition. Work under anhydrous conditions and ensure proper workup including quenching the reaction with a suitable reagent.
Why acetone cannot be use as organic solvent?
Acetone is the organic compound with the formula OC(CH3)2. The molecular shape of acetone makes it able to disolve many materials including plastics. This colorless, mobile, flammable liquid is the simplest example of the ketones. It is typically the solvent of choice for cleaning purposes in the laboratory owing to the fact that acetone is miscible with water, it is the solvent of choice for cleaning purposes in the laboratory. It is a common solvent for rinsing laboratory glassware because of its low cost, volatility, and ability to dissolve water. For similar reasons, acetone is also used as a drying agent.
Can you form a grignard reagent with 4-bromoaniline 4-bromobenzoic acid or 4-bromophenol when reacted with Mg in ether and why?
A Grignard reagent cannot be formed with 4-bromobenzoic acid as it has a carboxylic acid functional group that would not react with Mg in ether to form a Grignard reagent. Both 4-bromoaniline and 4-bromophenol can form Grignard reagents in the presence of Mg in ether due to the presence of a halogen atom (bromine) in their structures, which can undergo nucleophilic substitution reactions with Mg to form Grignard reagents.
How do you synthesize 1-phenyl-1-propanol using a grignard reaction?
Reaction of 1-propane-magnesia-bromide with benzaldehyde and destruction of the product with water yields to 1-phenyl-1-propanol.1) 1) Organikum, 21. Aufl., Wiley-VCH Verlag GmbH Weinheim 2001, S. 562
What is an inert solvent ... Also what would a inert solvent do like CCL4 treated with Br2?
Inert solvent is a solvent that does not react with your reaction system. means, it does not interfere between your reactants . . .Inert solvent like CCL4 does not do anything to Bromine, e.g. Bromine water, which is red-brown in colour, when added to CCL4 , its colour remains same.
What would be a common solvent for paint?
Most of them contain acetone.
Why is benzene formed during Grignard reactions using phenylmagnesium bromide?
Grignard reactions must be carried out in an anhydrous environment in an anhydrous solvent (e.g. anhydrous ether). Why? Grignard reagents behave essentially as a carbanion, and are extremely reactive. Therefore they cannot be carried out while acidic hydrogens, or other positive reactive centers are present (carbonyl compounds such as acetone) in the reaction mixture because there is no way to stop the Grignard from reacting with these other compounds rather than the desired reactant. If phenylmagnesium bromide were prepared, and ANY water was present in the reaction mixture phenylmagnesium bromide would not hesitate to react with water--stealing one of its hydrogens. This hydrogen would therefore replace the attached --MgBr to form benzene.
When nail-polish is dissolved in acetone which is the solute and which is the solvent?
The nail polish is the solute and the acetone would be the solvent. Sovents dissolve things & solutes are dissolved.
When nail polishes dissolved in acetone which substance is the solute and which is the solvent?
The nail polish is the solute and the acetone would be the solvent. Sovents dissolve things & solutes are dissolved.
If the ethyl ether used in the Grignard reaction is wet what byproduct would be form?
If the ethyl ether used in the Grignard reaction is wet (contains water), then the Grignard reagent formed will react with water to produce the corresponding alkane. The byproduct formed would be an alkane, along with magnesium hydroxide.
When nail polish is dissolved in acetone which substance is the solute and which is the solent?
the solvent in mainly Ethyl Acetate and the solute is ... I actually don't know. Mabe Google it.
Why do you use ammonium chloride rather than only water in the of the grignard reaction?
Ammonium chloride is used in the Grignard reaction to quench any remaining Grignard reagent and prevent unwanted side reactions. It reacts with the Grignard reagent to form an amine, which is stable and inert. Water alone would not be effective in stopping the reaction and could lead to byproducts.

What acts a solvent for chemical reactions?
A solvent that all the components of the reaction will dissolve into, and that won't become part of the reaction itself, would be a good solvent for a chemical reaction. This means that different reactions will require different solvents.

What would you use as a blank or reference if the solutions were made using 80 percent acetone in water as the solvent rather than pure water explain why?
Blanks are made using the same solvent used in your solutions. So, in this case, you would use 80 percent acetone in water. Blanks allow you to see what parts of your results are due to the solvent and what parts are due to the solute. If you used pure water as your blank, it would not show the effect of the 80 percent acetone in water on your results.
SN1 reaction of tert-butyl chloride with NaI in acetone?
So the since its SN1 it would be a two step process:1st step is the dissociation of the Cl so you get your carbocation.The second steps involves the Cl attaching to the NA+ and the I attaches with the carbocation.The acetone is not soluble with the NaCl so at the end of the reaction you'll have some precipiate from it.
