Statement-1 : Polybutadiene is an example of chain growth polymer.
Statement-2 : In chain growth polymers, the reactive particles may be free radicals or ions (cations or anions) to which monomers get added by a chain reaction.

Options

A. STATEMENT-1 is true, STATEMENT-2 is true and STATEMENT-2 is correct explanation for STATEMENT-1
B. STATEMENT-1 is true, STATEMENT-2 is true and STATEMENT-2 is not correct explanation for STATEMENT-1
C. STATEMENT-1 is true, STATEMENT-2 is false
D. STATEMENT-1 is false, STATEMENT-2 is true

Answer

To solve the question, we need to analyze both statements regarding polybutadiene and chain growth polymers.

### Step 1: Understanding Statement 1
- **Statement 1** claims that "Polybutadiene is an example of a chain growth polymer."
- **Analysis**: Polybutadiene is indeed a polymer formed through the polymerization of butadiene monomers. In chain growth polymerization, monomers add to a growing chain, which is characteristic of polybutadiene. Therefore, Statement 1 is **true**.

### Step 2: Understanding Statement 2
- **Statement 2** states that "In chain growth polymers, the reactive particles may be free radicals or ions (cations or anions) to which monomers get added by a chain reaction."
- **Analysis**: In chain growth polymerization, the initiation step often involves reactive species such as free radicals or ions that initiate the polymerization process. These reactive species add to the monomers, leading to a chain reaction where more monomers are added successively. This description accurately reflects the mechanism of chain growth polymerization. Therefore, Statement 2 is also **true**.

### Step 3: Conclusion
- Since both statements are true and Statement 2 correctly explains Statement 1, we conclude that both statements are valid.
- The correct option for this question is **Option A**: Both statements are true, and Statement 2 is the correct explanation for Statement 1.
