Class 10 Chemistry - Different types of Chemical Reactions

Question: What are different types of chemical reactions?

Answer: 

There are several different types of chemical reactions, including:

1. Combination or Synthesis Reaction: In this type of reaction, two or more substances combine to form a single product. The general form of this reaction is A + B → AB.

2. Decomposition Reaction: This type of reaction is the opposite of a combination reaction. Here, a single reactant breaks down into two or more simpler products. The general form of this reaction is AB → A + B.

3. Single Displacement or Substitution Reaction: This type of reaction involves the replacement of one element or ion in a compound by another element or ion. The general form of this reaction is A + BC → AC + B 

or 

A + BC → BA + C.

4. Double Displacement or Metathesis Reaction: In this type of reaction, the cations and anions of two different compounds switch places, resulting in the formation of two new compounds. The general form of this reaction is AB + CD → AD + CB.

5. Acid-Base or Neutralization Reaction: This type of reaction occurs when an acid reacts with a base to form a salt and water. The general form of this reaction is
HA + BOH → H2O + BA.

6. Redox or Oxidation-Reduction Reaction: 

When a substance gains oxygen or hydrogen is removed, such reaction is called oxidation. 
When a substance gains hydrogen or oxygen is removed, such reaction is called reduction.

e.g.

    A + O₂ → AO₂ (oxidation)

    BO₂ → B + O₂ (reduction)
