Vedclass · Answer

(B) The oxidizing power of halogens decreases down the group as the reduction potential decreases. Fluorine $(F_2)$ is the strongest oxidizing agent, while Iodine $(I_2)$ is the weakest. $A$ halogen with a higher reduction potential can displace a halide ion with a lower reduction potential from its salt solution. Since the reduction potential of $Cl_2$ is lower than that of $F_2$, $Cl_2$ cannot oxidize $F^-$ to $F_2$. Therefore, the reaction $Cl_2 + 2F^- \longrightarrow 2Cl^- + F_2$ is not spontaneous and does not occur.
