How will you convert ethyl bromide in to propane?
Ethyl bromide react with Grignard reagentCH3-CH2-Br + CH3-Mg_Br
What is the chemical equation for the preparation of ammonium bromide using potassium bromide and ammonium sulfate?
2 KBr + (NH4)2SO4 -> 2 NH4Br + K2SO4
What is the common name for MgBrO32?
There is so such thing as MgBrO32. There is, however, MgO, (magnesia) MgO2, (magnesium peroxide) and BrO2. (bromine dioxide) (I'm pretty sure this should be rendered as Mg(BrO3)2. If so, the name would be magnesium bromate, though if it has any "common name" I'm not aware of what it might be.)
Is magneisium a covalent bond?
Pure magnesium is a metal and the bonding is not covalent. Magnesium forms ionic bonds with more electronegative elements and this is its most common method of bonding. It does form covalent bonds for example with carbon in grignard reagents, for example ethyl magnesium bromide, C2H5MgBr.
What is the name of CuBr2?
Copper (II) Bromide
How do you do 1 1?
Reaction of cyclohexanone with 1-propyl magnesium bromide (a Grignard reagent) followed by hydrolysis.
How will you convert ethyl bromide in to propane?
Ethyl bromide react with Grignard reagentCH3-CH2-Br + CH3-Mg_Br
How do you synthesize 1-propylcyclohexan-1-ol?
Reaction of cyclohexanone with 1-propyl magnesium bromide (a Grignard reagent) followed by hydrolysis.
If ethyl benzoate used to prepare triphenylmethanol is wet what byproduct is formed?
THIS IS A DIRECT QUOTE FROM YAHOO ANSWERS:Benzene and magnesium hydroxide and magnesium bromide.I am betting you are doing a Grignard reactionEthyl benzoate + 2 phenylmagnesium bromide --> triphenylmethanol•MgBr saltif water is present, the grignard reacts with the water firstPhenylmagnesium bromide + H2O --> benzene + MgOHBr
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.
What is the chemical equation for the preparation of ammonium bromide using potassium bromide and ammonium sulfate?
2 KBr + (NH4)2SO4 -> 2 NH4Br + K2SO4
Write the formula of grignard reagent and state the polar character?
A Grignard reagent or Grignard compound is a chemical compound with the generic formula R−Mg−X, where X is a halogen and R is an organic group, normally an alkyl or aryl. Two typical examples are methylmagnesium chloride Cl−Mg−CH3 and phenylmagnesium bromide (C6H5)−Mg−Br. They are a subclass of the organomagnesium compounds.

How will you synthesise ethyl bromide into propionic acid?
Convert the ethyl bromide into Grignard's reagent, ethyl magnesium bromide then allow to react with dry ice (Solid carbon dioxide) then acidic hydrolysis produces the propionic acid. CH3-Br + Mg --- anhydrous ether---> CH3-CH2-Mg-Br CH3-CH2-Mg-Br + CO2 ----H+/H2O---> CH3-CH2-COOH

What is name of SnBr compound?

What is the name of the compound MgBr2 6H2O?
magnesium bromide hexahydrate
