Oh, dude, it's like this - polyethene is like the chill, laid-back version of ethene. It's already in a stable, happy relationship with itself, so it's not looking to get involved with bromine water drama. Ethene, on the other hand, is out there on the prowl, ready to react and cause a scene. So yeah, polyethene's just like, "No thanks, bromine water, I'm good."
Yes, however it doesn't require it either to react. ethene+bromine water→1,2-dibromoethane Ethane reacts with bromine only in the presence of UV forming bromoethane and hydrogen bromide.
Yes, ethene reacts with bromine water to form a colourless solution. In the presence of ethene, the orange-brown color of bromine water disappears as bromine is consumed in the addition reaction with ethene to form a colourless compound.
If this is supposed to be an alkene test, then no, hexane will not react with bromine water to take away its color as it is an alkane and therefore contains no double bonds. But bromine water will react with sodium hydroxide; bromine water contains either HCl or H2SO4, both of which will of course react with sodium hydroxide. In addition, I believe (from some experiments like this that I've done recently) that sodium hydroxide will actually react with the free bromine in the bromine water, as evidenced by the change in color from the orange-ish color of bromine water to a pale yellow.
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.
2,4,6-tribromophenol is formed by the loss of CO2 (decarbonylation).
One way to distinguish between ethene and ethyne is by performing a bromine water test. Ethene will decolorize bromine water, turning it from orange to colorless, while ethyne will not react with bromine water. This test takes advantage of the unsaturation in ethene that allows it to quickly react with bromine.
Bromine water test is used to show that ethene is unsaturated. In the presence of ethene, the red-brown color of bromine water disappears due to addition reaction with ethene, indicating its unsaturation.
Ethene can react with Bromine water - turns colourless
Yes, however it doesn't require it either to react. ethene+bromine water→1,2-dibromoethane Ethane reacts with bromine only in the presence of UV forming bromoethane and hydrogen bromide.
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.

it goes from a browny orange to colourless
To distinguish ethene from cyclohexane, one can assess their physical properties and reactivity. Ethene is an unsaturated hydrocarbon with a double bond, making it reactive with bromine water, which will decolorize upon contact, whereas cyclohexane, a saturated hydrocarbon, will not react in this way. Additionally, ethene is a gas at room temperature, while cyclohexane is a liquid, providing another means of differentiation.
no
