Each hydrogen peroxide molecule contains #2xxO-H# bonds.

Explanation:

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