1. Combination reaction - A reaction in which two substances or elements join together to form a single substance is called combination reaction. This type of reaction is also known as addition reaction.
example - C + =
2. Decomposition reaction - When a single reactant breaks down to form simpler substances is called a decomposition reaction.
example - - CaO +
3. Displacement reaction - A reaction in which a more reactive metal displaces a less reactive metal is called displacement reaction.
example - Fe + - + Cu
4. Double displacement reaction - A reaction in which there is an exchange of ions between reactants is called double displacement reaction.
example - + - + 2NaCl
5. Oxidation reaction - Addition of oxygen or removal of hydrogen in a reaction is called oxidation reaction.
example - 2Cu + - 2Cuo. Here copper is oxidised to copper oxide.
6. Reduction reaction - A reaction in which there is an addition of hydrogen or removal of oxygen is known as reduction reaction.
example - CuO + - Cu + . Here hydrogen is oxidised to form water.
there is one more....
Redox reaction - A reaction in which both oxidation and reduction takes place is known as redox reaction.
The example in oxidation and reduction reaction is the example of this reaction.
