Question

(B) The bond dissociation energy of $F-F$ is lower than expected due to high inter-electronic repulsion between the lone pairs of the small $F$ atoms.

Vedclass · Accepted Answer

$F-Cl$

Vedclass · Answer

(B) The bond dissociation energy of $F-F$ is lower than expected due to high inter-electronic repulsion between the lone pairs of the small $F$ atoms. However,among the given interhalogen options ($F-Cl$,$F-Br$,$Cl-Br$),the $F-F$ bond is often compared in terms of reactivity. In the context of bond strength for these specific molecules,the $F-Cl$ bond is stronger than $F-F$. Wait,re-evaluating: The $F-F$ bond is exceptionally weak due to lone pair repulsion. Among the options provided,$F-Cl$ has a stronger bond than $F-F$. Given the options,$F-Cl$ is the correct answer.

Which of the following has the strongest bond?
