Question:
Consider the following statements: Statement-I: Polystyrene is a thermosetting polymer. Statement-II: Bakelite is a thermoplastic polymer.
Consider the following statements: Statement-I: Polystyrene is a thermosetting polymer. Statement-II: Bakelite is a thermoplastic polymer.
Show Hint
Remember: Thermoplastics melt; Thermosets set permanently.
Updated On: Jun 3, 2026
- Both Statement-I and statement-II are correct
- Statement-I is correct but statement-II is not correct
- Statement-I is not correct but statement-II is correct
- Both Statement-I and statement-II are not correct
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
Polymers are classified as thermoplastic (soften on heating) or thermosetting (set into a hard shape on heating and cannot be remolded).
Step 2: Meaning
Polystyrene is a thermoplastic polymer because it can be repeatedly softened by heating and hardened by cooling. Bakelite is a cross-linked polymer, making it a classic example of a thermosetting polymer.
Step 3: Analysis
Statement-I claims Polystyrene is thermosetting (False). Statement-II claims Bakelite is thermoplastic (False).
Step 4: Conclusion
Since both statements are factually incorrect, option (D) is the right choice.
Final Answer: (D)
