However, isn't hydrogen bonding happens between between two molecules where each atom of hydrogen in them is attached to an electronegative element? If this is true, then how H2O2 has hydrogen bonding when it is not mentioned that it is attached to another H2O2 molecule? And I agree upon the fact that H2S2 is polar for being electronegative.
Hydrogen peroxide is the simplest kind of peroxide. It has an open book structure with O-O spins. Understand Structure, Properties, Preparation, Uses. Determine the Concentration of H2O2.
