1. i. Ionic compounds have low melting and boiling points.
2. ii. Ionic compounds are brittle and break into pieces when pressure is applied.
3. iii. Ionic compounds are solids and are somewhat hard because of the strong force of attraction between the positive and negative ions.
4. iv. Ionic compounds conduct electricity in the molten state.

• A. 1 only
• B. All
• C. None of these
• D. 1, 4

• The statement "Ionic compounds have low melting and boiling points" is not true.

• They typically exhibit high melting and boiling points due to the strong electrostatic forces of attraction between ions.
