$Cl_2$

Vedclass · Answer

(A) The bond dissociation enthalpy of halogens generally decreases down the group due to an increase in atomic size. However,$F_2$ has an exceptionally low bond dissociation enthalpy due to the high inter-electronic repulsion between the lone pairs of the small $F$ atoms. The correct order of bond dissociation enthalpy is: $I_2 Therefore,$Cl_2$ has the highest bond dissociation enthalpy.

Which of the following molecules has the highest bond dissociation enthalpy?
