Question

INTER HALOGEN COMPOUNDS ARE MORE REACTIVE THAN HALOGEN EXCEPT FLUORINE.EXPLAIN WHY

Answer 1

Answer:

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.

Explanation:

Answer 2

Interhalogen compounds are formed by ionic bonds due to difference in electronegativity. And they are more reactive because they can dissociate easily as they have weaker bonds as compared to pure halogen compounds possessing covalent bond which is formed by sharing of electrons .

The fact why fluorine is not a stable pure halogen compound is that it has a very small size due to which interelectronic repulsions are high making it unstable.

it is so because X-X bond in interhalogens is weaker than X-X bond in halogens except for F-F bond. (ii) ClF3 is used for the production of UF6.
