Question:
Which one of the following statements is not correct?
Which one of the following statements is not correct?
Show Hint
Electrical conduction in molten state is a characteristic property of ionic compounds, not covalent compounds.
Updated On: May 7, 2026
- Ionic bond is non-directional bond
- The maximum number of bond pairs between two atoms is \(3\)
- Covalent compounds conduct electricity in fused state
- Ionic compounds are generally soluble in water
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
Ionic compounds conduct electricity in molten or aqueous state because ions are free to move. Covalent compounds usually do not conduct electricity because they do not produce free ions.
Step 1: Ionic bonds are non-directional because electrostatic force acts in all directions.
Step 2: Ionic compounds are generally soluble in water due to ion-dipole interaction.
Step 3: Covalent compounds are made by sharing of electrons and generally do not form ions.
Step 4: Hence, covalent compounds do not generally conduct electricity even in fused state. Therefore, the incorrect statement is: \[ \boxed{\text{Covalent compounds conduct electricity in fused state}} \]
