FAQs on Mindmap: Polymers (Old NCERT) - Chemistry Class 12 - NEET

1. What are polymers?
Ans. Polymers are large molecules made up of repeating subunits called monomers. These monomers are chemically bonded together to form long chains or networks. Polymers can be found in various forms such as plastics, rubber, fibers, and even biopolymers found in living organisms.
2. How are polymers formed?
Ans. Polymers are formed through a process called polymerization. This process involves the reaction of monomers, which can be either naturally occurring or synthetic, to form long chains or networks. Polymerization can occur through various methods such as addition polymerization, condensation polymerization, or even through biological processes.
3. What are the properties of polymers?
Ans. Polymers exhibit a wide range of properties depending on their chemical structure and composition. Some common properties of polymers include high flexibility, low density, good electrical insulation, resistance to chemicals, and varying degrees of strength. These properties make polymers suitable for a wide range of applications in industries such as packaging, automotive, construction, and healthcare.
4. What are some common applications of polymers?
Ans. Polymers find extensive use in various industries and everyday products. Some common applications of polymers include plastic packaging materials, rubber tires, synthetic fibers for clothing, electrical insulation, automotive parts, medical devices, and even in construction materials such as PVC pipes and insulation foams.
5. What are the environmental concerns associated with polymers?
Ans. Polymers, especially synthetic ones, have raised concerns regarding their impact on the environment. The main concern is the slow degradation of certain polymers, leading to their accumulation in landfills and oceans. This can result in pollution and harm to marine life and ecosystems. Efforts are being made to develop biodegradable polymers and improve recycling processes to minimize the environmental footprint of polymers.
