Answer and Energy Required
The correct answer is (b). 2 O-H bond in H2O2 lie in different planes. What is the energy required to break all bonds in 1 mole of h2o2 molecules? The energy required to break one mole of hydrogen-hydrogen bonds in H2 is 436 kJ.
Longest Wavelength for Bond Breakage
What is the longest wavelength of light in nm that will break the diiodine bond? 842 nm. The longest wavelength that will break the O-O bond is 842 nm.

Comparison and Reduction
Is 2OH the same as H2O? 2HO means 2 hydrogen and 2 oxygen, H2O means only 2 hydrogen and 1 oxygen… In modern chemistry, we follow the Hill notation (a system devised by Edwin Allston Hill in 1900) for covalent compounds similar to the BODMAS rule for writing mathematical equations. Allora, when h2o2 is reduced the product is? When H2O2 serves as an oxidizing agent, the oxygen of hydrogen peroxide (that is present in -1 oxidation state) is reduced to H2O (-2 oxidation state).
