Why does polyethene not react in the same way with bromine water as ethene?
Wiki User
∙ 10y ago
As polyehtene is unsaturated(single bond) it does not react with bromine and there is no colour change.But bromine reacts with ethene and it becomes colourless.

Does ethene react with Bromine in the presence of UV light?
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.
Does ethene change from orange to colourless when it reacts with bromine water?
The ethene doesnt change from orange to colourless as ethene is already colourless but the bromine water turns from orange to colourless.
Does hexane and bromine water and sodium hydroxide solution react?
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.
What happens when bromine water is added to ethanol?
It will turn colorless because bromine is an unsaturated compound and unsaturated compound have double bonds
Why alkanes do not react with bromine water?
No, bromine will only add to alkenes, so NO addition reaction to alkanes. Subtitution on alkanes is not possible at standard conditions
Which tets coudl be used to distinguish between ethene and methane?
Ethene can react with Bromine water - turns colourless
Does ethene react with Bromine in the presence of UV light?
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.
What test is used to show that ethene is unsaturated?
by adding bromine water to the compound. if it is unsaturated, the red colour of the bromine water will fade quickly. if it is saturated, then it will not fade.
What happens if ethene is shaken with bromine water?
The solution will turn the orange bromine water into a colourless solution
Does ethene change from orange to colourless when it reacts with bromine water?
The ethene doesnt change from orange to colourless as ethene is already colourless but the bromine water turns from orange to colourless.
What happens when ethene is mixed with bromine water?
it goes from a browny orange to colourless
Does Bromine react with water?
no

Which metal don't react with bromine?
Bromine, which is represented by the chemical symbol Br, is very corrosive with most other elements. The only element I could find it does not react with is water.
