Question

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

• A. Solubility in water
• B. High melting and boiling points
• C. Electrical conductivity in solid-state
• D. Electrical conductivity in a molten state

Answer 1

The correct option is C

Electrical conductivity in solid-state

Explanation for the correct option:

(c ) Electrical conductivity in solid-state

• Ionic compounds are generated by the transfer of one or more electrons from one atom to the next, and these ions have a stronger attractive force than their repulsive forces.
• The ions are arranged in such a way that they have the least potential energy, resulting in a crystalline structure.
• As a result, the ions are unable to travel and conduct electricity.
• Hence this option is correct

Explanation for the incorrect options:

(a) Solubility in water

• ionic compounds are easily soluble in water
• Hence this option is correct

(b)High melting and boiling points

• ionic compounds have high melting and boiling point
• As it requires high energy to break ionic bonds
• Hence this option is correct

(d) Electrical conductivity in a molten state

• ionic compounds conduct electricity in molten state as it has free ions to carry charge
• Hence this option is correct

Hence the correct option is (c ) Electrical conductivity in solid-state
