Which of the following statements is not true about low density polythene ?

Options

A. Tough
B. Hard
C. Poor conductor of electricity
D. Highly branched structure

Explanation

To determine which statement is not true about low-density polythene (LDPE), let's analyze each option provided:

1. **Tough**: Low-density polythene is known for its toughness. This is true as LDPE can withstand stress and is used in various applications where flexibility and toughness are required.

2. **Hard**: Low-density polythene is not considered hard. In fact, it is known for being flexible and soft compared to high-density polythene (HDPE). Therefore, this statement is not true.

3. **Poor conductor of electricity**: LDPE is indeed a poor conductor of electricity. This characteristic is true and is one of the reasons it is used as an insulating material.

4. **Highly branched structure**: Low-density polythene has a highly branched structure, which contributes to its lower density and flexibility. This statement is also true.

Based on the analysis, the statement that is not true about low-density polythene is that it is "hard."

**Final Answer**: The statement that is not true about low-density polythene is **B. Hard**.
