When bromine water is shaken up with propene, the bromine water will decolorize due to the addition reaction between bromine and propene. This reaction results in the formation of a colorless 1,2-dibromoethane product.
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.
Bromine water is a dilute solution of bromine that is normally orange-brown in colour, but becomes colourless when shaken with an alkene. Alkenes can decolourise bromine water, while alkanes cannot.
Propene is an alkene, whereas propane is an alkane. Thus, propene is an unsaturated molecule, having a carbon-carbon double bond. If you add bromine water, an aqueous solution of bromine, to the test tubes, you can tell which is propene, the alkene. The bromine reacts with and saturates the double bonds in alkenes, and so decolourises. The bromine does not decolourise when added to an alkane as it does not react. So, in conclusion:Add bromine water (brown) to the test tubesIf the bromine water stays brown, the test tube contains propaneIf the bromine water goes colourless, the test tube contained propene.
When bromine water is shaken up with propane, a reaction occurs where the bromine water decolorizes. This is because bromine water is a reddish-brown color and reacts with the unsaturated bonds in propane to form colorless products. The reaction is a test for unsaturation in organic compounds, as alkenes and alkynes can react with bromine water to form colorless compounds, while alkanes do not undergo this reaction and the color of the bromine water remains unchanged.
If ethene is shaken with bromine water, the orange color of bromine water will be decolorized due to the addition reaction of bromine to ethene. This reaction results in the formation of a colorless compound called 1,2-dibromoethane.

tribromophenol is formed.
If ethene is shaken with bromine water, the orange color of bromine water will be decolorized due to the addition reaction of bromine to ethene. This reaction results in the formation of a colorless compound called 1,2-dibromoethane.
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.
When ethanol reacts with bromine water, the bromine is displaced by the oxygen in ethanol, resulting in decolorization of the bromine water. This reaction occurs because ethanol is a reducing agent, which means it can donate electrons to the bromine atoms, converting them from a colored form (brown/red) to a colorless form.
When bromine water is added to paraffin, no visible reaction occurs. Paraffin is a non-reactive hydrocarbon compound, so it does not undergo a chemical reaction with bromine. The bromine remains as a colored solution with no change in the paraffin.
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.
it goes from a browny orange to colourless
When bromine water is shaken with a saturated fat, the orange color of the bromine water will fade due to the reaction between the bromine and the unsaturated fatty acids in the fat. This reaction is a test for the presence of unsaturation in a compound.
