explain why,ethene decolourises bromine water where as ethane does not ?
Answers
Answer:
Bromine Water + Unsaturated Hydrocarbon -- Saturated Hydrocarbon
When bromine water is added to unsaturated hydrocarbon , it decolorizes bromine water.
but Ethane is a saturated hydrocarbon. So it does not Decolourise bromine water.
Explanation:
Ethene is an unsaturated compound.it has one double bond.When Bromine water(brown in colour) is added to ethene it reacts with ethene to form a new compound 1,2 dibromoethane which is colourless.The colour of bromine water is gone now.
Answer:
Bromine water decolourises unsaturated compounds. Ethene contains double bond and hence it is unsaturated.It reacts with Br to give colourless compound whereas ethaneis saturated compound. But Ethane is a saturated hydrocarbon. So it does not Decolourise bromine water.
