$F_{2} > Cl_{2} I_{2}$ (Order of bond energy)

(C) The correct order of bond dissociation energy for halogens is $Cl_{2} > Br_{2} > F_{2} > I_{2}$. $F_{2}$ has a lower bond energy than $Cl_{2}$ and $Br_{2}$ due to high inter-electronic repulsion between the lone pairs of the small $F$ atoms. Therefore,the order given in option $C$ $(F_{2} > Cl_{2} I_{2})$ is incorrect.
