Reactions of Main Group Elements with Halogens

WebAug 21, 2024 · In each case, a halogen higher in the group can oxidize the ions of one lower down. For example, chlorine can oxidize bromide ions to bromine: (3) Cl 2 + 2 Br − → 2 Cl − + Br 2. The bromine forms an orange solution. As shown below, chlorine can also oxidize iodide ions to iodine: (4) Cl 2 + 2 I − → 2 Cl − + I 2. WebThe fall in reactivity is because the halogens become less good oxidising agents as you go down the group.
