Question

calculate that oxidation number of h2o2 and o2f2

Answer 1

In h2o2 oxygen has the oxidation number of -1 as it acts as a peroxide. Upon solving, we can determine the oxidation number of hydrogen to be +1.

In o2f2 the oxidation number of fluorine is -1 (oxidation number of fluorine is always-1 in its compounds) . Upon solving we can determine the oxidation number of oxygen to be +1
