Double Bonds vs.Single Bonds We can compare the single O-O bond in H2O2 with the double O=O bond in O2. First,we find the structure of H2O2: H.0.0.H>H:0:0:H> H-O-O-H We know the structure of O2: :0=0: Experiment shows that the single O-O bond in hydrogen peroxide is both longer and weaker than the double bond between the same two oxygens in O2. Single bonds are longer and weaker than double bonds V-12Single bonds are longer and weaker than double bonds We can compare the single O O bond in H2O2 with the double O O bond in O2.
