Do Alkene decolourise bromine water?

Yes they do that. They are reacting together.

Would ethane decolorise bromine water?

Actually no...ethane ( Alkane class in general ) decolourise bromine water due to the absence of the double bond ( C=C ) ethene (alkenes in general ) will decolourise the bromine water..

Why does bromine water decolourise with SO2?

It's because, bromine water, being a good oxidising agent oxidises SO2 to H2SO4.

What simple chemical test will distinguish an alkene from an alkane?

Test both in bromine water. The unsaturated alkene will decolourise the bromine water.

Does cycloalkene decolourise bromine water?

Yes, just like the open chain alkenes.

Why does bromine water fade when testing for saturation?

Bromine reacts with the double / triple bonds giving typically a colourless compound. the bromine water therefore fades as the bromine reacts.

What you would see when orange bromine water is shaken with propene?

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.
