This can be ascribed to the greater van der Waals radius of iodine compared to bromine, 1.96 Å vs. 1.85 Å . On the other hand, the Br…O separations are all less than the Cl…O, even though the chlorine van der Waals radius is 0.09 Å less than the bromine. Again, secondary interactions may be involved.

Difference Between Bromine and Chlorine

Bromine is less reactive than chlorine. However, under normal conditions, bromine participates in multiple chemical interactions. Often in the chemical compounds bromine exhibits a -1 oxidation state, but it can also be in any odd positive oxidation state (+1, +3, +5, +7). Chlorine can be present in all oxidation states from -1 to +7, except +2.

Halogens as Oxidizing Agents

Chlorine, Bromine and Iodine. 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: Cl2 + 2Br− → 2Cl− +Br2 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:
