Question

Match the following

Column-A	Column-B
Nylon 6	Natural Rubber
Vulcanized Rubber	Cross Linked
cis-1,4-polyisoprene	Caprolactam
Polychloroprene	Neoprene.

Choose the correct answer from option given below

• A. a→ II, b→ III, c→ IV, d→I
• B. a→ III, b→II, c→I, d→ IV
• C. a→ III, b→ IV, c→I, d→ II
• D. a→ IV, b-III, c→ II, d→I

Answer 1

The Correct Option is B

To solve this matching-type question, we need to correctly match the terms in Column-A with their corresponding items in Column-B based on their scientific meaning and context. 

1. Nylon 6: Nylon 6 is a type of polyamide made from the monomer caprolactam. Therefore, Nylon 6 is associated with Caprolactam.
2. Vulcanized Rubber: Vulcanization is a chemical process for converting natural rubber or related polymers into more durable materials via the addition of sulfur or other equivalent curatives. This process introduces cross-links between individual polymer chains, hence Vulcanized Rubber is Cross Linked.
3. cis-1,4-polyisoprene: This is the scientific name for natural rubber. It is a naturally occurring polymer of isoprene. Therefore, cis-1,4-polyisoprene relates to Natural Rubber.
4. Polychloroprene: This is a synthetic rubber produced by polymerizing chloroprene, commonly known as Neoprene. Hence, Polychloroprene corresponds to Neoprene.

Upon matching, we get:

• Nylon 6 → Caprolactam
• Vulcanized Rubber → Cross Linked
• cis-1,4-polyisoprene → Natural Rubber
• Polychloroprene → Neoprene

Now, let's compare with the given options:

Correct Answer:

a → III, b → II, c → I, d → IV

 

This matches the associations we derived based on chemical knowledge:

• a: Nylon 6 → III: Caprolactam
• b: Vulcanized Rubber → II: Cross Linked
• c: cis-1,4-polyisoprene → I: Natural Rubber
• d: Polychloroprene → IV: Neoprene

This confirms that the correct option is indeed a → III, b → II, c → I, d → IV.
