Question

Match List I with List II

List-I	Polymer	List-II	Type/ Class
(A)	Nylon-2-Nylon-6	(I)	Thermosetting polymer
(B)	Buna-N	(II)	Biodegradable polymer
(C)	Urea-formaldehyde	(III)	Synthetic rubber resin
(D)	Dacron	(IV)	Polyester

Choose the correct answer from the options given below:

• A. (A)-(II), (B)-(I), (C)-(IV), (D)-(III)
• B. (A)-(II), (B)-(III), (C)-(I), (D)-(IV)
• C. (A)-(IV), (B)-(I), (C)-(III), (D)-(II)
• D. (A)-(IV), (B)-(III), (C)-(I), (D)-(II)

Hint:

Understanding the properties and applications of polymers helps in correctly identifying their types. For example, biodegradable polymers like Nylon-2-Nylon 6 decompose naturally, while synthetic rubbers like Buna-N are used for their elasticity

Answer 1

The Correct Option is B

Step 1: Analyze the Polymers:

• Nylon-2-Nylon-6: A biodegradable polymer, matching with (II).
• Buna-N: A synthetic rubber, matching with (III).
• Urea-Formaldehyde Resin: A thermosetting polymer, matching with (I).
• Dacron: A polyester, matching with (IV).

Conclusion:

The correct match is:

• (A) – (II)
• (B) – (III)
• (C) – (I)
• (D) – (IV)

Final Answer: (2)
