Based on the activity series provided, which reactants will form products? cap f is greater than Cl comma Cl is greater than Br comma Br is greater than cap i

A halogen can replace a less active halogen in a compound. The series ranks bromine above iodine, so Br₂ can displace iodine from CuI₂ and form products. In the other choices, the free halogen is less active than the halogen in the compound, so it cannot replace it.
