Question

Interhalogen compounds are more reactive than the individual halogens because

• A. they are prepared by direct combination of halogens
• B. $X - X'$ bond is weaker than $X-X$ or $X' - X'$ bonds
• C. they are thermally more stable than halogens
• D. there is a large difference in their electronegativity

Answer 1

Answer: (B)

$X - X'$ bond is weaker than $X-X$ or $X' - X'$ bonds

Answer 2

Since dissimilar halogens are combined in interhalogen compounds hence the bond between them $(X - X'$ bond$)$ is weaker than homoatomic halogen $(X - X$ or $X '-X '$ bonds$)$.
