Question

Which scientist name is associated with discovery of vulcanization?

• A. A.J. Heeger
• B. W.H. Carothers
• C. C. Goodyear
• D. MacDiarmid

Hint:

Vulcanization involves sulfur cross-linking, which greatly enhances the mechanical properties of natural rubber.

Answer 1

The Correct Option is C

Step 1: Understanding vulcanization.
Vulcanization is a chemical process used to improve the properties of natural rubber by heating it with sulfur. This process increases elasticity, strength, durability, and resistance to temperature changes, making rubber suitable for industrial and commercial use.
Step 2: Historical background.
The discovery of vulcanization was made accidentally in 1839 by Charles Goodyear. He observed that rubber mixed with sulfur and heated became tougher and more elastic instead of sticky and brittle. This discovery revolutionized the rubber industry.
Step 3: Analysis of options.
(A) A.J. Heeger: Known for conducting polymers, not vulcanization.
(B) W.H. Carothers: Known for nylon and polymer research, not vulcanization.
(C) C. Goodyear: Correct — He discovered the vulcanization process of rubber.
(D) MacDiarmid: Known for conductive polymers, not rubber vulcanization.
Step 4: Conclusion.
The scientist associated with the discovery of vulcanization is Charles Goodyear, making option (C) the correct answer.
