Top Polymers Questions for NEET
Polymers is one of the most straightforward and scoring chapters in NEET Chemistry. Most questions are directly based on NCERT, especially from types of polymers, classification, preparation methods, and uses. By mastering the Top 5 Polymers Questions, you can secure quick and easy marks in the exam with minimal effort.
Why Polymers is Important for NEET
Polymers is a theory-based chapter where direct questions are frequently asked. Topics like addition vs condensation polymers, biodegradable polymers, and synthetic rubbers are commonly tested. Practicing the Top 5 Polymers Questions ensures you can quickly revise key concepts and avoid silly mistakes in the exam.
Top 5 Polymers Questions (Important PYQs with Tricks)
Question 1: Addition vs Condensation Polymer
Which of the following is an addition polymer?
A. Nylon-6,6
B. Terylene
C. PVC
D. Bakelite
Answer: C
Explanation:
PVC (Polyvinyl chloride) is formed by addition polymerization of vinyl chloride monomers. Nylon-6,6 and Terylene are condensation polymers. This is a very common question in the Top 5 Polymers Questions.
Trick:
If small molecules like water or HCl are eliminated → condensation polymer. If not → addition polymer.
Question 2: Natural vs Synthetic Polymer
Which of the following is a natural polymer?
A. Nylon
B. Rubber
C. Teflon
D. PVC
Answer: B
Explanation:
Natural rubber is obtained from latex of rubber trees. Nylon, Teflon, and PVC are synthetic polymers. This is a direct NCERT-based concept in Top 5 Polymers Questions.
Question 3: Biodegradable Polymer
Which of the following is biodegradable?
A. PVC
B. Nylon-6
C. PHBV
D. Bakelite
Answer: C
Explanation:
PHBV (Poly-β-hydroxybutyrate-co-β-hydroxyvalerate) is a biodegradable polymer. Most synthetic polymers are non-biodegradable. This concept is frequently asked in Top 5 Polymers Questions.
Question 4: Elastomers
Which property is characteristic of elastomers?
A. High tensile strength
B. Elasticity
C. Brittleness
D. High melting point
Answer: B
Explanation:
Elastomers like rubber can stretch and return to their original shape due to weak intermolecular forces. This is a key concept in the Top 5 Polymers Questions.
Question 5: Polymer Structure
Which polymer is formed by condensation polymerization?
A. Polyethylene
B. PVC
C. Nylon-6,6
D. Polystyrene
Answer: C
Explanation:
Nylon-6,6 is formed by condensation of hexamethylenediamine and adipic acid with elimination of water. This is one of the most repeated Top 5 Polymers Questions.
Key Concepts You Must Remember
While preparing the Top 5 Polymers Questions, focus on classification of polymers (natural, synthetic, semi-synthetic), types of polymerization (addition and condensation), and properties of polymers such as elastomers, fibres, and plastics. Memorizing examples from NCERT is extremely important for this chapter.
Additional Practice Questions (Concept-Based Rapid Revision)
Question 6
Which polymer is used in non-stick cookware?
Answer: Teflon
Question 7
Which polymer is used in making ropes?
Answer: Nylon
Question 8
Which polymer is thermosetting?
Answer: Bakelite
Question 9
Which polymer is formed from ethene?
Answer: Polyethylene
Question 10
Which polymer is used in bulletproof materials?
Answer: Kevlar
Additional Practice Questions with Solutions
Question 11
Why are addition polymers stronger?
Solution:
They have long chains without weak linkages formed by elimination reactions.
Question 12
Why are thermosetting polymers hard?
Solution:
They have cross-linked structures, making them rigid and heat-resistant.
Question 13
Why is rubber elastic?
Solution:
Weak intermolecular forces allow chains to stretch and return to original shape.
Question 14
Why are biodegradable polymers important?
Solution:
They reduce environmental pollution by decomposing naturally.
Question 15
Why is Bakelite used in electrical switches?
Solution:
It is a good insulator and heat-resistant.
Final Revision Tips
To master the Top 5 Polymers Questions, revise NCERT examples thoroughly and focus on classification and uses. Avoid confusion between addition and condensation polymers by practicing repeatedly. Revisiting the Top 5 Polymers Questions will help you quickly recall concepts during the exam.
Consistent revision of the Top 5 Polymers Questions ensures accuracy and speed, helping you score full marks from this chapter.
