Question

Match the following: 

• A. A-III, B-II, C-I
• B. A-III, B-I, C-II
• C. A-II, B-I, C-III
• D. A-II, B-III, C-I

Hint:

- Homopolymers: Polymers made from a single type of monomer (e.g., Orlon).
- Copolymers: Polymers made from two or more different monomers (e.g., Buna-N).
- Condensation Polymers: Formed through step-growth polymerization with the elimination of a small molecule (e.g., Perlan-L).

Answer 1

The Correct Option is D

To solve this question, we need to correctly match the types of polymers from List-I with the appropriate examples from List-II.

Let's analyze each option:

1. Addition polymer – Homopolymer: A homopolymer is a polymer consisting of identical monomer units.
   • The example for this is Orlon, which is a polymer of acrylonitrile and fits the classification of an addition polymer – homopolymer.
2. Condensation polymer: This type of polymer is formed through a condensation reaction, where typically a small molecule, often water, is lost.
   • The example here is Perlan – L, which fits the category of a condensation polymer.
3. Addition polymer – Copolymer: A copolymer is composed of two or more different types of monomers.
   • Buna – N is a synthetic rubber made by polymerizing 1,3-butadiene and acrylonitrile, making it an addition polymer – copolymer.

Based on the analysis above, we can match each with its correct example:

• A-II: Addition polymer – Homopolymer matches with Orlon.
• B-III: Condensation polymer matches with Perlan – L.
• C-I: Addition polymer – Copolymer matches with Buna – N.

Therefore, the correct answer is: A-II, B-III, C-I.
