Question

Why are interhalogen compounds more reactive than Halogens?

Answer 1

Interhalogen compounds more reactive than Halogens:-

• Interhalogen compounds are compounds that have a chemical formula of $(\mathrm{X}-{\mathrm{X}}^{\text{'}})$, that is 2 different halogens.
• On the other hand, the halogen which is of $(\mathrm{X}-\mathrm{X})$type have 2 same halogens.
• As a result the bond strength of the interhalogen molecule is much less than that of halogen compounds.
• And we know that the more the bond strength is more difficult is it to break that bond, and the less reactive will be the molecule.
• Since here interhalogen compounds have weak bond strength, the bond tends to break more easily and thus is more reactive than halogens with $(\mathrm{X}-\mathrm{X})$type.
• Therefore, Interhalogen compounds are more reactive than Halogens.
• Example of interhalogen compounds:-$\mathrm{ICl},\mathrm{IBr}$
• Example of halogen compounds:-${\mathrm{Cl}}_2,{\mathrm{Br}}_2$
