FAQs on PPT: Polymers - Chemistry for JEE Main & Advanced

1. What are polymers and why are they important in the field of chemistry?
Ans. Polymers are large molecules composed of repeating structural units called monomers. They are important in chemistry because of their versatility in properties and applications, such as in plastics, fibers, and rubber.
2. How are polymers classified based on their structure?
Ans. Polymers can be classified as either natural or synthetic based on their origin. They can also be classified as homopolymers or copolymers based on the type of monomers present in the polymer chain.
3. What are some common examples of polymers used in everyday life?
Ans. Common examples of polymers used in everyday life include polyethylene (used in plastic bags), polypropylene (used in packaging and textiles), and polyvinyl chloride (used in pipes and vinyl records).
4. How are polymers synthesized in the laboratory?
Ans. Polymers can be synthesized through various polymerization techniques, such as addition polymerization (where monomers are added together) or condensation polymerization (where monomers are joined by eliminating small molecules like water).
5. How do the properties of polymers vary based on their molecular structure?
Ans. The properties of polymers, such as strength, flexibility, and thermal stability, depend on factors like the type of monomers, polymer chain length, and branching. These properties can be tailored for specific applications by controlling the polymerization process.
