Bromine (Br2) reacts with alkenes to form dibromoalkanes. By adding Br2 in CCl4 to the two compounds, the compound with the carbon-carbon double bond (alkene) will turn a red-brown color indicating the presence of the double bond. The other compound, without the double bond, will remain colorless. Therefore, choice C would distinguish between the two compounds.
