(9) Cage like Oxide:
(1) Normal oxides:
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 anhydride
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.
(2) Sesqui oxides:
The oxides in which number of oxygen atoms pet central atoms is
found to be 3/2 .And it may be ionic, covalent or missed oxides.Mostly M2O3
type Oxides (Corundum structure) are sesqui Oxides. Where M+2= Al, Ga, Ti, V, Cr, Fe,
The etc.
Examples , B2O3, N2O3,
Al2O3 ( covalent oxide) Fe2O3
(ionic oxide) Pb2O3 (mixed oxide)
(3) Mixed Oxides:
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 etc.
(4) Peroxides:
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.
(5) Super Oxides:
The oxides in which
oxidati state of oxygen atom always -1/2, and super oxides are always ionic and
paramagnetic.
For
examples KO2 , PbO2, (NH4)O2 etc.
KO2 =>
k+[O-O]-. Have following character
Bond pair -2
Lone pair -2
Hybri- sp2, linear non
planner and bond angle not applicable.
(6) Suboxides:
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.
(7) Perovskite
oxides:
ABO3 type Oxides are also called Perovskite for examples CaTiO3 And
BaTiO3.
(8) Spinel Oxide:
(7) Case Oxides:
P4, P4O4,
P4O10, P4S3, P4S10,
N4(CH2)6
