The Oxides in which oxidation state of central atom is found to be one of the it's common oxidation state. The are also called acid anhydrides because on dissolving them into water oxygen acid is formed in which oxidation state of central atom is found to be same as present in Oxide.
Examples: B2O3, CO2, N2O3, N2O5, SO2, SO3, Cl2O7, XeO3, XeO4 etc.
The oxides in which calculated oxidation state of central
atom is more than maximum oxidation state of central atom due to the presence
of peroxide linkage.
For examples, H2O2, Na2O2, BaO2, PbO2, CrO5 etc.
The oxides contains more oxygen atoms as compare to central atoms
and according to valency requirements of central atoms number of oxygen atoms
are not sufficient.
For examples B2O3, C3O2,
C12O9, Pb3O, Rb9O2, Cs11O3
etc.
The oxides in which oxidation state of oxygen atom is found to be
it's uncommon oxidation state on central atom. Mixed oxides on dissolving in
water undergo "disproportionation"
For examples B2O3, ClO2, Cl2O7 , N2O5 , As2O4 etc.
