Which of the following is an example of a synthetic polymer? A. Wool B. Silk C. Nylon D. Cellulose 2. Polythene is a polymer that can be used for making A. toys B. water pipes C. plastic bags D. electricity wires 3. State one important property of polymers. 4. PVC is produced from chloroethene monomers. Use a suitable chemical equation to show the formation of polyvinyl chloride. 5. Polyesters is an example of a biodegradable polymer. (i) Define the term biodegradable polymer. (ii) List two pollution problems caused by non-biodegradable polymers.
Understand the Problem
The question asks about synthetic polymers, their uses, properties, and the formation of specific polymers, making it a chemistry-related inquiry focused on consumer chemistry.
Answer
1. Nylon. 2. Plastic bags. 3. Flexible and strong. 4. n(CH2=CHCl) → {-CH2-CHCl-}n. 5(i). Broken down by microorganisms. 5(ii). Landfill and ocean pollution.
- Nylon. 2. Plastic bags. 3. Polymers can be flexible and strong. 4. n(CH2=CHCl) → {-CH2-CHCl-}n (polyvinyl chloride). 5(i). Biodegradable polymers can be broken down by microorganisms. 5(ii). Non-biodegradable polymers cause landfill accumulation and ocean pollution.
Answer for screen readers
- Nylon. 2. Plastic bags. 3. Polymers can be flexible and strong. 4. n(CH2=CHCl) → {-CH2-CHCl-}n (polyvinyl chloride). 5(i). Biodegradable polymers can be broken down by microorganisms. 5(ii). Non-biodegradable polymers cause landfill accumulation and ocean pollution.
More Information
Synthetic polymers include materials like nylon and polyethylene. Polymers have properties like flexibility and strength. Biodegradable polymers degrade through biological processes, whereas non-biodegradable polymers contribute to pollution.
Tips
Remember that synthetic polymers are man-made, unlike natural polymers like wool or silk.
