i think there is a mistake on the C2 mc mark scheme march 2012 as C2H4 definitely turns bromine water colourless as it is an unsaturated alkene.

The C2 mc mark scheme is correct. The answer for question 35 is "D". C2H4 is an unsaturated hydrocarbon, an alkene called ethene, which has a C=C that allows for the addition of Br2.

On shaking ORANGE bromine water with anunsaturated hydrocarbon, the bromine water is DECOLOURISED (becomes colourless).
