Question

Why are interhalogen compounds more reactive than the related elemental halogens?

Explain why:

Interhalogen compounds are more reactive than the related elemental halogens.

Answer 1

1. Interhalogen compounds have weaker X-Y bonds compared to the stronger X-X or X-Y bonds in elemental halogens.
2. These weaker bonds break more easily, making interhalogen compounds more reactive.
3. Interhalogen compounds are covalent and often reactive oxidising agents.
4. Their structure and bond differences lead to higher chemical reactivity than elemental halogens.

Answer 2

Interhalogen compounds are more reactive than the related elemental halogens because they are polar and have lower bond energies.
