The reaction of iron(II) salts with bromine is a redox reaction forming iron(III).
The aqueous reaction with bromine water is typical:-
2Fe2+ + Br2 -> 2Fe3+ + 2Br-
If you started with iron(II) bromide, iron(III) bromide would be formed
Bromine reacts with the double / triple bonds giving typically a colourless compound. the bromine water therefore fades as the bromine reacts.
K3P, potassium phosphide
Hydrogen chloride will be produced
No. When bromine (aq) reacts with cyclohexene, the compound is now saturated, and will no longer have C=C bonds, thus it is unable to exhibit cis-trans isomerism.
2 bromophenol, 4 bromophenol and hydrogen bromide are formed
The compound formed is simply NaF
Na2Se
Bromine reacts with the double / triple bonds giving typically a colourless compound. the bromine water therefore fades as the bromine reacts.
Sodium peroxide is the principal product and it is Na2O2.
K3P, potassium phosphide
Na3P sodium phosphide
Hydrogen chloride will be produced
No!! Benzene wont de colourise bromine water although it is an unsaturated compound ,as it is an aromatic compound and it does not undergo addition reaction.
Sodium bromide(NaBr) is formed
No. When bromine (aq) reacts with cyclohexene, the compound is now saturated, and will no longer have C=C bonds, thus it is unable to exhibit cis-trans isomerism.
2 bromophenol, 4 bromophenol and hydrogen bromide are formed
I'm not sure but I know that when sodium reacts with bromine it does that.
