Question

Quizplus · Accepted Answer

The reagent Br/CCl4 can be used to distinguish between alkenes and alkanes. In the second compound, there is an exocyclic alkene (CH=CH-) that is not present in the first compound. Treatment with Br/CCl4 will result in addition of the halogen to the alkene in the second compound, while the first compound will not react. The other reagents listed would not specifically target the difference between the two compounds.
