What happens when bromine water is added to oil?
When bromine water is added to oil, if the oil contains unsaturated bonds, the reddish-brown color of the bromine water will be reduced as the bromine molecules add across the double bonds in a chemical reaction called bromination. This reaction is used to test for the presence of unsaturation in organic compounds like alkenes or alkynes.
What happens between bromine and water when you add hydrochloric acid?
When hydrochloric acid is added to a mixture of bromine and water, bromine will react with hydrochloric acid to form hydrogen bromide and hypobromous acid. This reaction can then proceed further to form bromine chloride and bromine, depending on the conditions present.
What happens when bromine is added to water?
When bromine is added to water, it reacts to form hypobromous acid (HBrO) and hydrobromic acid (HBr). This can further dissociate to form bromide ions (Br-) and hypobromite ions (OBr-). The overall reaction can be summarized as follows: Br2 + H2O → HBrO + HBr
What happens when bromine water is added to ethanol?
When bromine water is added to ethanol, the bromine will react with the ethanol forming 2-bromoethanol. The reaction occurs via nucleophilic substitution where the bromine reacts with the -OH group of ethanol. This reaction can be used as a test to distinguish between primary, secondary, and tertiary alcohols.
What happens when bromine and sodium combine?
When bromine and sodium combine, they react to form sodium bromide. This is a salt that is water soluble and a common source of bromine in various chemical applications. The reaction between bromine and sodium is a redox reaction where sodium loses an electron to bromine.
What happens when bromine water is added to phenol?
tribromophenol is formed.
What happens when bromine water reacts with alkenes?
Bromine water reacts with alkenes through an electrophilic addition reaction where the pi bond of the alkene breaks, and bromine atoms are added to the carbon atoms. This reaction results in the decolorization of the bromine water, changing it from orange to colorless.
What happens when a drop of water is added to calcium carbide in the presence of bromine solution?
Probable tetrabromoethane is formed.
What happens if you mix cooking oil with bromine water?
The bromine water turns from orange to colourless, as it is breaking the double bonds. When the oil becomes saturated, any more bromine water that is added will not turn colourless.
What happens when paraffin is poured into water?
When paraffin is poured into water, it will float because paraffin is less dense than water. This is because paraffin is a type of hydrocarbon that is nonpolar and does not mix with water, which is a polar molecule. The two substances will not dissolve or mix together.
What reaction happens between bromine water and iron sulphate?
When bromine water is added to iron sulfate, the bromine oxidizes the iron(II) ions to iron(III) ions, forming a brown precipitate of iron(III) bromide. This reaction is a redox reaction, where the bromine is reduced and the iron is oxidized.
What happens when bromine water is added to oil?
When bromine water is added to oil, if the oil contains unsaturated bonds, the reddish-brown color of the bromine water will be reduced as the bromine molecules add across the double bonds in a chemical reaction called bromination. This reaction is used to test for the presence of unsaturation in organic compounds like alkenes or alkynes.
What colour change occurs when propene is added in bromine water?
Bromine water is originally orange-brown in color. When propene is added to bromine water, the orange-brown color fades as the bromine molecules react with the carbon-carbon double bond in propene. This reaction leads to the decolorization of the bromine water to a colorless solution.

What happens when the bromine solution is first added to cyclohexane?
At room temperature, the halogens like bromine don't react with cyclohexane. Hence the dark brown color of the bromine water remains. When heated, the -H atoms are replaced with -Br(substitution reaction).
