Question

Interhalogen compounds are more reactive than the individual halogen because:

• A. two halogens are present in place of one
• B. here bond energy is less than bond energy of the halogen molecule
• C. they are nore ionic
• D. they carry more energy

Answer 1

The correct option is B here bond energy is less than bond energy of the halogen molecule

When two different halogens react with each other, interhalogen compounds are formed.
General composition like$X{X}^{\prime },X{X}_3^{\prime },X{X}_5^{\prime },X{X}_7^{\prime }$
where $X$ is halogen of larger size and $X^{\prime }$ of smaller size, $X$ is more electropositive than $X^{\prime }$
Inter halogen are more reactive than halogen (except Fluorine) because $X-X^{\prime }$ bond in interhalogens is weaker than $X-X$ bond in halogen except $F-F$ bond. So the correct option is (b).
