Question

Match List I and List II

List II	List II
A. Elastomeric polymer	I. Urea formaldehyde resin
B. Fibre Polymer	II. Polystyrene
C. Thermosetting Polymer	III. Polyester
D. Thermoplastic Polymer	IV. Neoprene

Choose the correct answer from the options given below :

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

Answer 1

The Correct Option is B

To correctly match polymers in List I with their corresponding type from List II, we must understand the characteristics and typical applications of each category given:

1. Elastomeric Polymer: These polymers are typically flexible, elastic, and rubber-like in nature. A common example of an elastomeric polymer is Neoprene, known for its elasticity and used in products like wetsuits and gaskets.
2. Fibre Polymer: These polymers tend to form fibers and have high tensile strength. Polyester is known for being made into fibers and widely used in textiles.
3. Thermosetting Polymer: These polymers form irreversible bonds upon curing and, once set, cannot be remelted. Urea formaldehyde resin is a well-known thermosetting polymer, used in adhesives and molded articles.
4. Thermoplastic Polymer: These polymers can be remelted and reshaped, providing versatility in reshaping. Polystyrene is a common thermoplastic known for being lightweight and used in packaging and disposable goods.

Given this understanding, let's match based on the properties:

• A. Elastomeric Polymer should match with IV. Neoprene.
• B. Fibre Polymer should match with III. Polyester.
• C. Thermosetting Polymer should match with I. Urea formaldehyde resin.
• D. Thermoplastic Polymer should match with II. Polystyrene.

Therefore, the correct matching is A-IV, B-III, C-I, D-II, which corresponds to the correct answer given in the options.
