Based on the reactivity of the halogens, which of these displacement reactions is possible?

The reactivity of halogens is a crucial factor in determining whether a displacement reaction can occur. The general rule is that a more reactive halogen can displace a less reactive halogen from its compound.

Reactivity Series of Halogens

In the reactivity series, the halogens are ranked as follows from most reactive to least reactive:

1. Fluorine (F₂)
2. Chlorine (Cl₂)
3. Bromine (Br₂)
4. Iodine (I₂)

Displacement Reactions

Based on the reactivity series:

1. Fluorine can displace chlorine, bromine, and iodine.
2. Chlorine can displace bromine and iodine but cannot displace fluorine.
3. Bromine can displace iodine but cannot displace chlorine or fluorine.
4. Iodine cannot displace any of the other halogens.

Conclusion

To determine if a specific displacement reaction is possible, compare the reactivity of the halogens in the reaction. If the halogen attempting to displace another is higher in the reactivity series, the reaction can occur; otherwise, it cannot.
