Question

Calculate the oxidation number of O in the following compounds:

a) H₂O₂ b) KO₂ c) OF₂​

Answer 1

Answer:

a) we can calculate oxidation of number oxygen atom in H2O2 by taking the sum of oxidation number of all atoms of H2O2. so the oxidation number of oxygen in hydrogen peroxide (H2O2) is -1.

b) since ko2 is a neutral molecule so it has a net charge equal to zero on the compound. Therefore the oxidation of o in ko2 is -1/2.

c) oxidation state of OF2 is +2
