This section focuses on Polymers, a vital topic in Organic Chemistry that connects molecular structure with material properties and real-world applications. Polymers are large macromolecules formed by the repeated linking of smaller units called monomers, and they form the foundation of plastics, synthetic fibers, rubbers, and many modern materials.
Designed for Class 11–12 students, NEET/JEE aspirants, and undergraduate learners, this category emphasizes polymer classification, polymerization mechanisms, structure–property relationships, and industrial relevance, with strong alignment to NCERT-based concepts and exam preparation.
In this section, you will study:
• Classification of polymers (natural, synthetic, semi-synthetic)
• Types of polymerization: addition and condensation
• Copolymers and biodegradable polymers
• Thermoplastics and thermosetting polymers
• Elastomers and fibers
• Molecular mass and degree of polymerization
• Structure–property relationships
• Industrial preparation and applications of important polymers
• Environmental concerns and green polymer alternatives
The content is structured to build conceptual clarity, strengthen reaction understanding, and improve analytical skills for exam-oriented questions and MCQs.
Mastering Polymers helps you understand how organic chemistry shapes modern materials science and prepares you effectively for school examinations, competitive exams, and higher studies in chemistry and material sciences.
Q. What is the IUPAC name for the polymer formed from the monomer 1,3-butadiene?
A.
Polybutadiene
B.
Polybuta-1,3-diene
C.
Poly(1,3-butadiene)
D.
Polybutylene
Solution
The correct IUPAC name for the polymer formed from 1,3-butadiene is Poly(1,3-butadiene), which indicates the structure of the repeating unit.
Q. Which of the following is a characteristic of condensation polymerization?
A.
It produces small molecules as byproducts
B.
It requires high temperatures
C.
It only involves alkenes
D.
It is a one-step process
Solution
Condensation polymerization typically involves the reaction of two different monomers, resulting in the release of small molecules such as water or methanol.
Correct Answer:
A
— It produces small molecules as byproducts
Q. Which of the following statements about thermoplastics is true?
A.
They can be reshaped upon heating
B.
They are chemically cross-linked
C.
They have a fixed shape
D.
They are always biodegradable
Solution
Thermoplastics can be reshaped upon heating, allowing them to be molded into various forms, unlike thermosetting plastics which cannot be reshaped once set.
Correct Answer:
A
— They can be reshaped upon heating
