Question

Which of the following is not true about ionic compounds?

• A. Ionic compounds have high boiling point.
• B. Ionic compounds have low melting point.
• C. Ionic compounds are generally soluble in water.
• D. Ionic compounds conduct electricity in their molten state.

Answer 1

The correct option is B Ionic compounds have low melting point.

• Ionic compounds have high melting and boiling points. This is because of the strong force of attraction acting between the positive and negative ions.
• These compounds are generally soluble in water and insoluble in solvents such as kerosene, petrol, etc.
• These compounds conduct electricity in their molten state as the ions move freely and conduct electricity.
