Cartain materials such as turpentine oil, unsaturated organic compound, phosophorus, metals such as `Zn`, and `Pb`, etc., can absorb `O_(2)` from air in the presence of `H_(2)O`, which is converted to absorb `O_(2)` from air in the presence of `H_(2)O`, which is converted to `H_(2)O_(2)`. This is called autoxidation. Intermolecular redox reactions are those in which one molecule is oxidised and the other is reduced. Intramolecular redox reactions are those in which oen atom of a molecule is oxidised and the other atom is reduced.

    `{:(2e^(-)+Cl_(2) rarr2Cl^(ө)(“Reduction”)),(” “2ClO^(ө)+2e^(-) (“Oxidation”)),(” “[Disproportionation]):}`

    It is also a disproportional reaction.
    `[overset(+1)Hoverset(+1)(Cu)overset(-1xx2)(Cl_(2))]`
    `e^-)+Cu^(1+)rarrCu (“Reduction”)`
    `Cu^(1+)rarrCu^(2+)+e^(-)(“oxidation”)`
    c. It is a also a disproportionation reduction. `HCHO` is oxidised to `HCOO^(ө)` and reduced to `CH_(3)OH`.
    d. It is none since the oxidation state of `Mg` is `+2` in both reactant and product. Similarly, the oxidation states of `C` and `O` are `+4` and `-2` in both reactant and product.
