What makes hydrogen peroxide a polar molecule?

1 Answer

Each hydrogen peroxide molecule contains 2×OH bonds.

Explanation:

As in water, the OH bonds are polar, i.e there is substantial charge separation. Of course, the OO bond itself is non-polar so that when we assign oxidation states to this molecule, we have H+I and OI. Nevertheless, we would rightly predict that hydrogen peroxide is polar.
