An experiment was run similar to the experiment described in the Hydrocarbon Reactions Experiment. The results of the experiments are given below: Observations after addition of Observations after addition of Unknown Time for Colour Change Bromine water Bromine water + UV light 1 colour remains yellow red colour changed to clear 2 colour remains yellow red colour became lighter but never cleared (sec) 725 1310 to go lighter 3 colour slowly changed to clear red colour immediately became upon shaking clear The unknowns are either: benzene; cyclohexane; cyclohexene; or toluene 1 From the results identify the unknowns. Unknown 1 is toluene. Unknown 1 is benzene. Unknown 1 is cyclohexane. Unknown 1 is cyclohexene.
