Which of the following statements about low density polythene is false ?

Options

A. It is a poor conductor of electricity.
B. Its synthesis requires dioxygen or a peroxide initiator as a catalyst.
C. It is used in the manufacture of buckets, dust-bins etc.
D. Its synthesis requires high pressure.

Answer

To determine which statement about low-density polyethylene (LDPE) is false, we need to analyze each statement provided in the question.

### Step-by-Step Solution:

1. **Understanding LDPE**:
- LDPE stands for low-density polyethylene. It is a type of polymer made from the polymerization of ethylene (ethene) monomers.

2. **Analyzing the Statements**:
- **Statement 1**: "It is a poor conductor of electricity."
- This statement is true. LDPE is an insulator and does not conduct electricity well.

- **Statement 2**: "Its synthesis requires dioxygen or a peroxide initiator as a catalyst."
- This statement is also true. The polymerization of ethylene to form LDPE typically involves free radical mechanisms, which can be initiated by dioxygen or peroxides.

- **Statement 3**: "It is used in the manufacture of buckets and dustbins."
- This statement is false. LDPE is not typically used for making buckets and dustbins; these items are usually made from high-density polyethylene (HDPE), which is stronger and more rigid. LDPE is more commonly used for plastic bags, food wraps, and flexible packaging.

- **Statement 4**: "Synthesis requires a very high temperature and a high pressure."
- This statement is true. The polymerization of LDPE does require high temperatures and pressures to facilitate the reaction.

3. **Conclusion**:
- Based on the analysis, the false statement about low-density polyethylene is **Statement 3**: "It is used in the manufacture of buckets and dustbins."

### Final Answer:
The false statement about low-density polyethylene (LDPE) is that it is used in the manufacture of buckets and dustbins.
