The study of polymers is an essential part of the Chemistry curriculum for Class 12 students. Polymers are large, complex molecules made up of repeating units called monomers. These monomers are linked together through chemical bonds, forming long chains that can have a variety of properties and uses. Polymers are found in everyday items like plastic bottles, rubber tires, and even the DNA in our cells. Understanding the structure and behavior of polymers helps us appreciate their role in both natural and synthetic materials, making them a crucial topic in modern science and industry.
This collection of multiple-choice questions (MCQs) with answers is designed to help Class 12 students deepen their knowledge of polymers. Each question is followed by the correct answer, providing an immediate feedback mechanism to aid learning and retention. By working through these questions, students can test their understanding of polymer concepts, such as types of polymers, their synthesis, and their applications. This practice will not only prepare students for their exams but also give them a solid foundation in one of the most versatile and widely used materials in the world
