Question:
Identify the incorrect set from the following:
Identify the incorrect set from the following:
Show Hint
Ionic solids like MgO have high melting points and conduct electricity in molten state, unlike covalent solids.
Updated On: Mar 24, 2025
- SiO₂, covalent solid, insulator, high melting point
- MgO, covalent solid, insulator, high melting point
- H₂O (ice), molecular solid, insulator, low melting point
- Ag(s), metallic solid, conductor, high melting point
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Classifications
- SiO₂ is correctly classified as a covalent solid.
- MgO is incorrectly classified as a covalent solid (it is an ionic solid).
- H₂O (ice) is correctly classified as a molecular solid.
- Ag is correctly classified as a metallic solid.
Thus, MgO's classification is incorrect.
- SiO₂ is correctly classified as a covalent solid.
- MgO is incorrectly classified as a covalent solid (it is an ionic solid).
- H₂O (ice) is correctly classified as a molecular solid.
- Ag is correctly classified as a metallic solid.
Thus, MgO's classification is incorrect.
