Vedclass · Answer

(D) The feasibility of a displacement reaction involving halogens depends on their standard reduction potentials. $A$ halogen with a higher reduction potential can displace a halogen with a lower reduction potential from its salt solution.The order of oxidizing power (reduction potential) of halogens is: $F_2 > Cl_2 > Br_2 > I_2$.$1$. $Cl_2$ can displace $Br^-$ and $I^-$.$2$. $Br_2$ can displace $I^-$.$3$. $I_2$ cannot displace $Cl^-$ or $Br^-$.In option $D$,$I_2$ is attempting to displace $Br^-$ from $KBr$. Since $I_2$ is a weaker oxidizing agent than $Br_2$,this reaction is not feasible.
