Does pentene decolourise bromine solution?
Pentene is an unstaturdated hydrocarbon (One that does not have many possible side branches) It reacts readily with halogens to form new substances. In this case, bromine reacts with pentene in an addition reaction, this changes pentene into 1,1-dibromopentane. Thus, removing bromine from the solution, hence the distinct orange color is removed.
When benzene reacts with bromine water will it decolourise bromine water or not?
No!! Benzene wont de colourise bromine water although it is an unsaturated compound ,as it is an aromatic compound and it does not undergo addition reaction.
What changes in color occur when bromine or KMnO4 reacts with an alkane?
Purple to colourless
What changes in color occur when bromine or KMnO4 reacts with an alkene?
The purple KMnO4 is decolourise
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 changes in color when bromine reacts with an alkyne?
It changes from brown to colorless. Br2 has a brown color before it reacts with the alkene, forming a dibromoalkane as the alkene opens up its double bond and bromine joins up with that bond. The Br-Br bond is broken, hence removing the brown color. In reality, the appearance of bromine water depends on its concentration.
When bromine reacts with sodium to form a white solid is it a physical or chemical change?
chemical change a physical change changes the apperance chemicals changes change the substance

Why does alkyne decolourise bromine water?
The alkyne reacts with bromine removing it from the aqueous solution.
Does bromine react with soduim?
Yes: Bromine reacts with sodium to form sodium bromide.
