NCERT Solutions Class 12 Chemistry Chapter 15 Polymers
CBSE Class 12 Chemistry Chapter 15 is dedicated to ‘Polymers’ and their use in various areas. Different applications rely on mechanical qualities such as tensile strength, elasticity, toughness, etc. Intermolecular interactions, such as van Der Waals forces and hydrogen bonds in the Polymer, regulate these mechanical properties.
The polymer chains are likewise held together by these forces. As a result, polymers are divided into four sub-groups based on the magnitude of their intermolecular forces.
Students will learn about two different forms of polymerisation reactions in CBSE NCERT Solutions Class 12 Chemistry Chapter 15. Polymers constitute the backbone of five key industries, according to the NCERT Class 12 Chemistry Chapter 15:
- Plastic
- Elastomers
- Fibres
- Paints
- Varnishes
Key Topics Covered in NCERT Solutions Class 12 Chemistry Chapter 15
The Chapter covers the process of creating polymers from monomers and synthesising them. Polymers, monomers, and polymerisation are all explained there.
After that, it looks for distinctions between polymer Classes and different types of polymerisation methods. It also emphasises the construction of polymers from monomers and bifunctional polymers. Finally, it discusses the utilisation of polymers and their applications in everyday life.
