The correct Answer is:
To solve the assertion-reason question regarding Teflon, we will analyze both the assertion and the reason step by step. ### Step 1: Analyze the Assertion The assertion states that "Teflon has high thermal stability and chemical inertness." - Teflon, known chemically as polytetrafluoroethylene (PTFE), is indeed recognized for its high thermal stability. It can withstand high temperatures without decomposing. - Additionally, Teflon is chemically inert due to the strong carbon-fluorine (C-F) bonds in its structure. This means that it does not react easily with most chemicals, making it suitable for various applications, including non-stick cookware. **Conclusion for Step 1:** The assertion is true. ### Step 2: Analyze the Reason The reason states that "Teflon is a thermosetting polymer." - Thermosetting polymers are materials that, once set into a given shape, cannot be remolded or reshaped upon heating. They undergo a chemical change when heated, which makes them rigid and inflexible. - Teflon, however, is classified as a thermoplastic polymer. This means that it can be melted and reshaped upon heating. It does not undergo a chemical change that would make it permanently set. **Conclusion for Step 2:** The reason is false. ### Step 3: Determine the Relationship Now we need to determine if the reason provided is a correct explanation for the assertion. - Since the assertion is true and the reason is false, the reason does not explain the assertion. ### Final Conclusion - The assertion is true, and the reason is false. Therefore, the correct answer to the assertion-reason question is that the assertion is true, but the reason is not a correct explanation of the assertion. ---
