The compounds of oxygen and other elements are called oxides.

·         Types of oxides:

 

 

 

 

1.     Acidic oxides: Non- metallic oxides are usually acidic in nature.

2.     Basic oxides: Metallic oxides are mostly basic in nature. Basic oxides dissolve in water forming bases e.g.,

3.     Amphoteric oxides: They show characteristics of both acidic as well as basic oxides.

4.     Neutral oxides: These oxides are neither acidic nor basic. Example: Co, NO and N2O

 

Ozone 

1.     Preparation: It is prepared by passing silent electric discharge through pure and dry oxygen 10 – 15 % oxygen is converted to ozone.

2.     Structure of Ozone: Ozone has angular structure. Both O = O bonds are of equal bond length due to resonance.
