The correct Answer is:
To analyze the question, we need to evaluate both the assertion and the reason provided. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that SiC (Silicon Carbide) has a higher melting point than NaCl (Sodium Chloride). - **Fact**: SiC is known to have a very high melting point, typically around 2700°C, while NaCl has a melting point of about 801°C. 2. **Understanding the Reason**: - The reason states that SiC has stronger electrostatic forces of attraction. - **Fact**: SiC is a covalent network solid, meaning it is held together by strong covalent bonds rather than electrostatic forces typical of ionic compounds like NaCl. 3. **Analyzing the Nature of Bonds**: - SiC consists of covalent bonds, which are generally stronger than the ionic bonds found in NaCl. - Ionic compounds like NaCl are held together by electrostatic forces between positively and negatively charged ions, but SiC does not primarily rely on these forces. 4. **Conclusion**: - The assertion is true because SiC does indeed have a higher melting point than NaCl. - The reason is false because SiC does not have stronger electrostatic forces of attraction; it has strong covalent bonds instead. 5. **Final Answer**: - Based on the analysis, the correct option is that the assertion is true, but the reason is false.
