    Propane and bromine equation oxidation reduction?

    Propane and bromine equation oxidation reduction? propane is shaken vigorously with a solution of bromine water in the presence of uV, its asking for the oxidation and reduction equations but it didn't work out. I can get the full equation bu the oxidation numbers don't work out with the carbons.
