Question

Match the LIST-I with LIST-II:

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

Hint:

Think of the "Product": Polybutadiene = Tires (Rubber); Polypropylene = Bottles (Plastic); Nylon = Clothing/Rope (Fibre); PF = Circuit boards/Glue (Resin).

Answer 1

The Correct Option is D

Concept: Polymers are industrially categorized based on their physical properties and end-use applications into elastomers (rubbers), plastics, fibers, and resins.

Step 1: Match A (Polybutadiene).
Polybutadiene (A) is a highly elastic synthetic polymer used primarily in tires, making it a classic Rubber (III).

Step 2: Match B (Polypropylene).
Polypropylene (B) is a versatile thermoplastic used in packaging, automotive parts, and containers, categorized as Plastics (IV).

Step 3: Match C (Phenol Formaldehyde).
Phenol Formaldehyde (PF) (C), commonly known as Bakelite, is a thermosetting polymer often used as an adhesive or molding compound, categorized as a Resin (I).

Step 4: Match D (Nylon 66).
Nylon 66 (D) has high tensile strength and can be drawn into long, thin threads, which is why its primary classification is Fibre (II).
