FAQs on Advantages and Disadvantages of Plastic in Chemistry
1. What are the advantages and disadvantages of plastic?
The main advantages of plastic are durability, low cost, and chemical resistance, while the key disadvantages of plastic are pollution, non-biodegradability, and harmful environmental effects.
- Advantages: lightweight, corrosion-resistant, waterproof, good electrical insulator, easily moulded into shapes.
- Disadvantages: non-biodegradable, releases toxic gases on burning, causes soil and water pollution, harms marine life.
2. Why is plastic considered non-biodegradable?
Plastic is considered non-biodegradable because most synthetic polymers have strong carbon–carbon (C–C) bonds that microorganisms cannot easily break down.
- Common plastics like polyethylene and polypropylene consist of long hydrocarbon chains.
- These polymers resist enzymatic degradation by bacteria and fungi.
- As a result, plastics can persist in the environment for hundreds of years.
3. What are the main chemical properties of plastics?
The main chemical properties of plastics include high molecular weight, polymer structure, chemical resistance, and low reactivity.
- Plastics are made of repeating units called monomers joined by polymerization.
- They are generally resistant to acids, bases, and water.
- Most are poor conductors of electricity and heat.
- They can soften on heating (thermoplastics) or remain rigid (thermosetting plastics).
4. What are the environmental disadvantages of plastic?
The major environmental disadvantages of plastic include long-term pollution, microplastic formation, and toxic emissions.
