Question

Which among the following polymers belongs to the class elastomers?

• A. Polystyrene
• B. Nylon
• C. Neoprene
• D. Bakelite

Hint:

Elastomers are polymers that can stretch and return to their original shape, like Neoprene, which is commonly used in flexible products.

Answer 1

The Correct Option is C

Step 1: Understanding elastomers.
Elastomers are polymers that have elastic properties, meaning they can stretch and return to their original shape. They typically have low intermolecular forces and are used in products like rubber.
Step 2: Analyzing the options.
(A) Polystyrene: Polystyrene is a thermoplastic polymer, not an elastomer.
(B) Nylon: Nylon is a thermoplastic polymer, used in fibers and plastics, not elastomers.
(C) Neoprene: Neoprene is a synthetic rubber that is used as an elastomer in various applications like gaskets, seals, and wetsuits.
(D) Bakelite: Bakelite is a thermosetting plastic, not an elastomer.
Step 3: Conclusion.
The correct answer is (C) Neoprene, which is an elastomer.
