Question

Which one of the following properties is generally not exhibited by ionic compounds?

[1 mark]

• A. High melting and boiling points
• B. Soluble in water
• C. Conduction of electricity in solid state
• D. Solid and hard in nature

Answer 1

The correct option is C Conduction of electricity in solid state

Conduction of electricity occurs due to movement of ions. In the solid state, ions are held together by strong electrostatic forces and they are not free to move around. Hence, ionic compounds do not conduct electricity in the solid state.

Due to the strong electrostatic force of attraction between ions, ionic compounds have high melting and boiling points, and they are also solid and hard in nature.

As ionic compounds are polar, they are soluble in water.
