FAQs on Polymers Class 11 Notes Chemistry Chapter 15

1. What are polymers and why are they important in various industries?
Ans. Polymers are large molecules composed of repeating subunits called monomers. They are important in various industries because of their unique properties such as high strength, flexibility, and resistance to chemicals. They are used in manufacturing plastic products, textiles, packaging materials, and even medical devices.
2. How are polymers classified based on their structure?
Ans. Polymers can be classified into three main categories based on their structure: linear polymers, branched polymers, and cross-linked polymers. Linear polymers have a straight chain-like structure, branched polymers have side chains branching off from the main chain, and cross-linked polymers have chemical bonds connecting different polymer chains.
3. What are the different methods of polymerization?
Ans. Polymerization is the process of joining monomers together to form polymers. There are two main methods of polymerization: addition polymerization and condensation polymerization. In addition polymerization, monomers react together without the elimination of any byproducts, while in condensation polymerization, small molecules, such as water or alcohol, are eliminated as byproducts during the polymerization process.
4. How do polymers contribute to environmental pollution?
Ans. Polymers, particularly single-use plastics, contribute to environmental pollution due to their resistance to degradation. When disposed of improperly, they can end up in landfills or oceans, taking hundreds of years to decompose. This leads to issues such as marine pollution and harm to wildlife. However, efforts are being made to develop biodegradable polymers and promote recycling to reduce their environmental impact.
5. How are polymers used in the field of medicine?
Ans. Polymers have a wide range of applications in the field of medicine. They are used to create medical implants, drug delivery systems, and wound dressings. Biodegradable polymers are used for sutures that dissolve over time, reducing the need for removal. Polymers also play a crucial role in tissue engineering, where they are used as scaffolds to support the growth of new tissues or organs.
