Acidic oxide	Basic oxide	Amphoteric oxide	Neutral oxide
Acidic oxides (also known as acid anhydrides) are formed when non-metal reacts with oxygen. They do not react with acid. They react with base form salt and water.	Basic oxides (also known as basic anhydrides) are formed when a metal reacts with oxygen. They react with acid to form salt and water. They do not react with base.	Amphoteric oxides are metallic oxides that can react with both acids and bases to form salt and water. It exhibits acidic as well as basic characteristics.	Neutral oxides show neither acidic nor basic characteristics. They do not react with acids or bases. They are also called neutral compound of oxygen.
Among the given oxides SO₂,CO₂, and NO₂ are acidic oxides	Among the given ones Na₂O, CuO, and FeO are basic oxides.	PbO is the amphoteric oxide.	CO and N₂O are neutral oxides.
