Statement-1 . HDPE is a branched chain polymer.
Statement-2. it is prepared by addition polymerization.

Options

A. Statement -1 is True , Statement -2 is True , Statement-2 is a correct explanation for Statement-1.
B. Statement-1 is True , Statement-2 is True , Statement-2 is not a correct explanation for Statement-1.
C. Statement-1 is True , Statement-2 is False.
D. Statement-1 is False , Statement-2 is True.

Explanation

To solve the question regarding the statements about HDPE (High-Density Polyethylene), we need to analyze both statements provided:

**Step 1: Analyze Statement 1**
- Statement 1 claims that HDPE is a branched chain polymer.
- HDPE is actually a linear polymer, characterized by its tightly packed molecular structure, which results in high density and strength. Therefore, Statement 1 is **false**.

**Step 2: Analyze Statement 2**
- Statement 2 claims that HDPE is prepared by addition polymerization.
- HDPE is indeed produced through the addition polymerization of ethylene (ethene), which involves the opening of the double bond in ethylene molecules to form long chains. Therefore, Statement 2 is **true**.

**Step 3: Conclusion**
- Since Statement 1 is false and Statement 2 is true, we conclude that the correct answer to the question is that only Statement 2 is correct.

**Final Answer:**
- Statement 1 is false, and Statement 2 is true. Therefore, the correct option is that Statement 1 is incorrect while Statement 2 is correct.
