उत्तर
| Ionic compounds | Covalent compounds |
| These contain electrovalent or ionic bond. | These contain covalent bond. |
| They are generally crystalline solids. | They are generally volatile liquids or gases. |
| They have high melting and boiling points. | They have low melting and boiling points. |
| They are bad conductors of electricity in solid state but are good conductors in the molten or aqueous states. | They do not conduct electricity. |
| They are generally soluble in water but insoluble in organic solvents. | They are generally soluble in organic solvents but insoluble in water. |
| They consist of ions. So, their reactions in solutions are fast. | They consist of molecules. So, their reactions in solutions are slow. |
