how strong is o2
Best Answer: F2 and Cl2 are diatomic molecules in which the atoms are bonded by single bonds. In O2 molecule, two atoms of oxygen are bonded by double bonds. As double bonds are stronger than single bonds, common sense says that O2 has the strongest bonds of them all. Hope that helps!
One would expect an O-O bond to be stronger than an S-S bond due to oxygen's smaller radius, however O-O has a bond energy of 142 kJ/mol compared to the 266 kJ/mol of S-S.
