Upper halogen can replace lower halogen from their compounds solution because a more electronegative halogen displaces less electronegative halogen from its halide.

Q. When $I_{2}$ is passed through $K Cl, K F$ and $K B r$ solutions:

$C l_{2}$ and $B r_{2}$ are evolved

$C l_{2}$ is evolved

$C l_{2}, B r_{2}$ and $F_{2}$ are evolved

none of the above
