Which halogen can displace chloride ions (Cl-)?

Explanation:
Displacement in halogens happens when a more reactive halogen can take the place of a less reactive halide in a compound. Among the halogens, reactivity is highest at the top of the group and gets weaker as you go down. Fluorine sits at the top, so it’s the strongest oxidizer and can push chloride ions to form chlorine gas while itself becoming fluoride. The reaction can be written as F2 + 2 Cl- → 2 F- + Cl2. Since fluorine is more reactive than chlorine, bromine, and iodine, it is the one capable of displacing chloride from its salts.
