Lewis structure for ozone has formal charges on two oxygens. The average O–O bond order in ozone is 1.5, which is smaller than the bond order of 2 for molecular oxygen. A smaller bond order means that the bond energy in ozone is smaller than in molecular oxygen, which means it takes less energy to break the bond.
