Question

Give two examples of synthetic rubber.

Hint:

Synthetic rubbers are derived from petroleum-based monomers and designed for specific industrial applications.

Answer 1

Step 1: Definition.
Synthetic rubbers are man-made polymers with elastic properties similar to natural rubber. They are obtained by polymerization of various monomers.
Step 2: Examples.
1. Buna-S (Styrene-butadiene rubber): Formed by copolymerization of 1,3-butadiene and styrene.
2. Neoprene: Formed by polymerization of chloroprene (2-chloro-1,3-butadiene).
Step 3: Uses.
- Buna-S is used in automobile tires.
- Neoprene is resistant to oil and chemicals and used for making hoses and gaskets.
