In a lab experiment I added Br2 to hydrocarbons cyclohexane, cyclohexene, and toluene. A loss of color would indicate a reaction took place. Only the cyclohexene lost color and turned clear. I guess this means that the Br2 broke the cyclohexenes double bonds but why didn't bromine react with the other two hydrocarbons?

Br2 adds across the double bond in cyclohexene. Cyclohexane and aromatic hydrocarbons (toluene) don't react in the4 cold and with no uv light.
