Why the unsaturated compound decolourises with bromine?

bromine water is oxidising in nature. it removes the double bonds and attaches itself to the alkene.


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

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


What is seen when bromine water is shaken with an unsaturated fat?

i think the unsaturated fat decolourises it :/


Do Alkene decolourise bromine water?

Yes they do that. They are reacting together.


What test can you carry out to differentiate between two test tubes one containing propane and propene?

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.


What happens when a bromine solution is added to an alkene?

alkenes will discolour bromine wateras the alkene reacts with it


What color does bromine water go when it reacts with an alkene?

Firstly, there is a discharge of reddish brown colour due to bromine which then turns colourless.


What test is used to distinguish between ethene and methane?

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.


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.
