Question:
Identify the correct set
Identify the correct set
Show Hint
Network solids tend to have high melting points and are usually insulators because they do not have free electrons or ions for conduction.
Updated On: Mar 3, 2026
- \( \text{SiO}_2 \) - ionic solid - conductor - high melting point
- \( \text{SiO}_2 \) - network solid - conductor - low melting point
- \( \text{SiO}_2 \) - network solid - insulator - high melting point
- \( \text{NaCl} \) - ionic solid - insulator in solid state - high melting point
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: SiO\(_2\) forms a network solid due to strong covalent bonding between oxygen and silicon atoms. It does not conduct electricity because there are no free-moving electrons or ions in its structure, hence it is an insulator in the solid state.
Step 2: The high melting point of SiO\(_2\) is due to the strong covalent bonds between the atoms in the network structure.
Thus, the correct option is (3).
