Question

Why interhalogen compound are more reactive than the halogen compound explain?

Answer 1

Hello❤

The inter halogens are generally more reactive than halogens except F. This is because A-X bonds in interhalogens are weaker than the X-X bonds in dihalogen molecules. Reaction of inter halogens are similar to halogens. Hydrolysis of interhalogen compounds give halogen acid and oxy-acid.

Answer 2

The interhalogen compounds are more reactive since the bonds (A-X) are weaker than the halogen atom bonds (X-X).

• The explanation for this is that the electronegativity of atoms in a compound of diahalogen is the same whereas that of atoms in interhalogen compounds is different.
• Therefore, the bond in interhalogen compounds is polarized which makes it easier to break. For example, the bond between ICl is weaker than I2 because the atom of ICl is more polarized because of a difference in the two atoms' electronegativity.
