Statement -1: High density polythene is form when addittion polymerisation of ethene takes place in a hydrocarbon solvent in the presence of a catalyst Ziegler-Natta catalyst at a temperature of 333k to 343k and under a pressure of 6-7 atmosphere.
Statement -2: High density polythene consists of linear molecules and has a high density due to closed packing and it is used for manufacturing buckets, dustbins, bottles.
select correct option regarding these statements.

Options

A. Both statements are correct and statement-2 is the correct explanation for the statement -1
B. Both statements are correct and statement-2 is not the correct explanation for the statement -1
C. statement-1 is incorrect but the statement-2 is correct
D. Both statements are incorrect

Answer

To solve the problem, we need to analyze both statements regarding high-density polyethylene (HDPE) and determine their correctness.

### Step-by-Step Solution:

**Step 1: Analyze Statement 1**
- **Statement 1** claims that high-density polyethylene is formed through the addition polymerization of ethylene in a hydrocarbon solvent using a Ziegler-Natta catalyst at temperatures between 333 K to 343 K and under pressures of 6-7 atmospheres.
- **Analysis**: This statement is correct. HDPE is indeed produced via addition polymerization of ethylene, and the conditions mentioned (temperature and pressure) are suitable for this process. The Ziegler-Natta catalyst is specifically used to facilitate this polymerization, leading to the formation of HDPE.

**Step 2: Analyze Statement 2**
- **Statement 2** states that high-density polyethylene consists of linear molecules and has a high density due to close packing, and it is used for manufacturing buckets, dustbins, and bottles.
- **Analysis**: This statement is also correct. HDPE is characterized by its linear molecular structure, which allows for efficient packing and results in a high density. The applications mentioned (buckets, dustbins, bottles) are typical uses for HDPE.

**Step 3: Determine the Relationship Between the Statements**
- Since both statements are correct, we need to assess whether Statement 2 provides a correct explanation for Statement 1.
- **Explanation**: Statement 2 explains the properties of HDPE that arise from the conditions described in Statement 1. The linear structure resulting from the polymerization conditions leads to high density due to close packing.

**Conclusion**:
Both statements are correct, and Statement 2 correctly explains Statement 1.

### Final Answer:
The correct option is: **Both statements are correct and Statement 2 is the correct explanation for Statement 1.**
