The resulting mixture will turn reddish-brown in colour
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.
The solution will turn the orange bromine water into a colourless solution
Ethanol dissolves in water, as the polar ethanol molecules form hydrogen bonds with water molecules.

tribromophenol is formed.
the solution decolourised
nothing happens but you can add iodine then it will change coulur

Liquid bromine is the Real Bromine, while Bromine water is a mixture of Bromine and Water
Jesus is re-incarnated.
it goes from a browny orange to colourless
