Vedclass · Answer

(D) The reactivity of halogens decreases down the group $(F_2 > Cl_2 > Br_2 > I_2)$.An element with higher electronegativity and higher oxidation potential can displace an element with lower electronegativity from its salt solution.Since $I_2$ is the least reactive among the given halogens,it cannot displace $Cl^-$,$Br^-$,or $F^-$ from their respective salt solutions ($KCl$,$KBr$,$KF$).Therefore,no reaction occurs.

When $I_2$ is passed through $KCl$,$KF$,and $KBr$ solutions,what happens?
