All alkenes decolourise bromine water.
Benzene will not decolourise bromine water as it does not undergo addition reaction. It is highly saturated due to presence electron cloud above and below it.
it cant decolourise
The ethene doesnt change from orange to colourless as ethene is already colourless but the bromine water turns from orange to colourless.
It's because, bromine water, being a good oxidising agent oxidises SO2 to H2SO4.
Actually no...ethane ( Alkane class in general ) decolourise bromine water due to the absence of the double bond ( C=C )...so ethene (alkenes in general ) will decolourise the bromine water..

The alkyne reacts with bromine removing it from the aqueous solution.
Yes they do that. They are reacting together.

The ethene doesnt change from orange to colourless as ethene is already colourless but the bromine water turns from orange to colourless.
The ethene reacts with the bromine and the solution turns colourless (from its original orange colour).
It's because, bromine water, being a good oxidising agent oxidises SO2 to H2SO4.
Test both in bromine water. The unsaturated alkene will decolourise the bromine water.
Ethene is an unsaturated substance since it is alkene and has one double bond, we can use bromine water to test ethene. Yellow bromine water turns colourless if the substance is ethene. If it is methane which is alkane ( not alkene ), bromine will stay yellow.
Yes, just like the open chain alkenes.
