Vedclass · Answer

(C) The correct order of bond dissociation enthalpy for halogens is $Cl_2 > Br_2 > F_2 > I_2$. Due to the small size of the fluorine atom,the lone pairs of electrons on the two fluorine atoms in $F_2$ experience significant inter-electronic repulsion. This makes the $F-F$ bond weaker than the $Cl-Cl$ and $Br-Br$ bonds,resulting in a lower bond dissociation enthalpy for $F_2$ compared to $Cl_2$ and $Br_2$.

The correct order of bond dissociation enthalpy of halogens is:
