Due to the presence of strong electrostatic forces of attraction between ions, ionic compounds :

Options

A. Have high melting and boiling points
B. Conduct electricity in solid state
C. Dissolve in kerosene
D. All of these

Explanation

To solve the question regarding the properties of ionic compounds due to the presence of strong electrostatic forces of attraction between ions, we will analyze the options provided and determine which statements are true.

### Step-by-Step Solution:

1. **Understanding Ionic Compounds**: Ionic compounds are formed when there is a transfer of electrons from one atom to another, resulting in the formation of positively charged ions (cations) and negatively charged ions (anions). The strong electrostatic forces of attraction between these oppositely charged ions hold the compound together.

**Hint**: Remember that ionic compounds consist of charged particles that attract each other.

2. **Analyzing the First Option**: The first statement claims that ionic compounds have a high melting and boiling point. This is true because the strong electrostatic forces between the ions require a significant amount of energy to overcome when changing states from solid to liquid (melting) or liquid to gas (boiling).

**Hint**: Consider how strong forces affect the energy needed to change states.

3. **Analyzing the Second Option**: The second statement suggests that ionic compounds conduct electricity in the solid state. This is incorrect. In the solid state, the ions are fixed in place within the crystal lattice structure and cannot move freely. Therefore, they cannot conduct electricity.

**Hint**: Think about the mobility of ions in different states of matter.

4. **Analyzing the Third Option**: The third statement claims that ionic compounds dissolve in kerosene. This is also incorrect because kerosene is a non-polar solvent, and ionic compounds are polar. According to the principle "like dissolves like," ionic compounds will not dissolve in non-polar solvents.

**Hint**: Recall the principle of solubility regarding polar and non-polar substances.

5. **Conclusion**: Based on the analysis:
- The first option is correct: Ionic compounds have a high melting and boiling point.
- The second and third options are incorrect.

### Final Answer:
The correct statement is that ionic compounds have a high melting and boiling point due to the strong electrostatic forces of attraction between the ions.
