Natural and Synthetic like Polythene, Nylon, Polyesters, Bakelite, Rubber — Predicted 2026
AI-Predicted Question Angles for UPSC 2026
Monomer Identification and Polymerization Type
highThis is a perennial favorite in NEET. Questions will likely ask to identify the monomer(s) of a given polymer (e.g., 'What are the monomers of Terylene?') or to classify a polymer based on its formation mechanism (e.g., 'Which of these is an addition polymer?'). Students must be able to recall the specific building blocks and the process for each major polymer. The trap often lies in confusing similar-sounding monomers or polymers, such as distinguishing between Nylon-6 and Nylon-6,6 monomers.
Properties and Applications of Specific Polymers
highNEET frequently tests the practical utility and characteristic properties of polymers. Expect questions like 'Which polymer is best suited for making electrical switches?' (Bakelite) or 'Which polymer is known for its high tensile strength and used in ropes?' (Nylon). Understanding the link between a polymer's structure/type (e.g., thermosetting vs. thermoplastic) and its real-world application is crucial. This requires memorizing key properties and uses for each polymer covered.
Distinction between Natural and Synthetic Polymers, and Vulcanization
mediumQuestions often test the fundamental classification of polymers and the specific process of vulcanization for natural rubber. For instance, a question might ask to identify a natural polymer from a list of synthetic ones, or to explain the purpose of vulcanization. Understanding the monomer of natural rubber (isoprene) and the effect of sulfur cross-linking is a common test point. The distinction between *cis*- and *trans*-polyisoprene and their implications for properties could also be a subtle point of inquiry.
