Question

What is the term used to describe the process, discovered by Goodyear, of adding sulfur to heated rubber?

• A. Oxidation
• B. Polymerization
• C. Vulcanization
• D. Distillation

Hint:

Associate Goodyear with vulcanization and improved rubber products.
Remember vulcanization is essential for practical uses of rubber.

Answer 1

The Correct Option is C

Vulcanization is a chemical process discovered by Charles Goodyear in 1839, involving heating rubber with sulfur to improve elasticity, strength, and durability.
Step 1: Problem with raw rubber
Raw rubber is sticky and deforms easily. Vulcanization stabilizes it, making rubber useful for products like tires and footwear.
Step 2: Effect of sulfur
Sulfur forms cross-links between rubber molecules, enhancing mechanical properties.
Hence, option (C) is correct.
