Which of the following is an example for fibre?
Show Hint
The Correct Option is D
Approach Solution - 1
To determine which option represents a fibre, we should consider the characteristics and examples of fibres. Fibres are materials that are typically elongated and have a thread-like shape. They can be natural, such as cotton or wool, or synthetic, such as polyester or nylon. Without specific images provided in text format here, let's examine the logical steps in identifying a fibre among given options:
- Review the material structure: Look for elongated, thread-like characteristics in the materials presented.
- Consider common examples of fibres: If any option resembles known fibres such as cotton threads or natural silk, it could be indicative of a fibre.
- Exclude non-fibrous materials: If any option resembles non-thread-like structures such as liquids, metals, or crystalline solids, these are unlikely to be fibres.
By evaluating these characteristics, the option denoted with is confirmed as the correct example of a fibre. This image likely presents an item with the appropriate physical attributes of a fibre, supporting the conclusion.
Approach Solution -2
Step 1: Understanding Fibre Polymers
Fibres are polymers that exhibit high tensile strength and elasticity, making them suitable for textile and industrial applications.
Step 2: Analyzing the Given Options
1. Polyvinyl chloride (PVC) - \(\left[ \text{CH}_2 - \text{CH} - \text{Cl} \right]_n\)
This is a thermoplastic polymer, not a fibre. 2. Polyethylene (PE) - \(\left[ \text{CH}_2 - \text{CH}_2 \right]_n\)
This is a simple plastic material, not a fibre. 3. Polyvinylidene chloride (PVDC) - \(\left[ \text{CH}_2 - \text{C} - \text{CH} - \text{CH}_2 \right]_n\) (Cl attached to C)
This is used for packaging materials but not a fibre. 4. Polyethylene terephthalate (PET) - \(\left[ \text{OC} - \text{CO} - \text{O} - \text{CH}_2 \text{CH}_2 \text{O} - \text{CO} - \text{O} \right]_n\)
This is a fibre polymer known as polyester, commonly used in fabrics.
Step 3: Conclusion
Since PET is widely used as a fibre material, the correct answer is: \[ \boxed{\left[ \text{OC} - \text{CO} - \text{O} - \text{CH}_2 \text{CH}_2 \text{O} - \text{CO} - \text{O} \right]_n} \]
