Solution
The bond energies of Chlorine, Bromine, and Iodine decreases down the group as the size of the atom increases. The bond energy of Fluorine, is, however, lower than those of Chlorine and Bromine because of interelectronic repulsions present in the small atom of Fluorine. So, Chlorine will have the highest bond energy.
