प्रश्न
Compare the properties of ionic compounds and covalent compounds.
List four differences in properties between covalent compounds and ionic compounds.
उत्तर
| Sr. No. | Ionic compound | Covalent compound |
| 1. | Ionic compounds are usually crystalline solids. | Covalent compounds are usually liquids or gases. |
| 2. | Ionic compounds have high melting and boiling points. | Covalent compounds have low melting and boiling points. |
| 3. | Ionic compounds are usually soluble in water. | Covalent compounds are usually insoluble in water. |
| 4. | Ionic compounds conduct electricity when dissolved in water or melted. | Covalent compounds do not conduct electricity. |
| 5. | Ionic compounds are insoluble in organic solvents. | Covalent compounds are soluble in organic solvents. |
Notes
Students should refer to the answer according to their questions.
