Solution
| Sr. No. | Basis of Distinction | Electrovalent (Ionic) Compounds | Covalent compounds |
| 1. | Physical State | They are generally crystalline solids. | They are generally volatile liquids or gases. |
| 2. | Melting and Boiling Points | They have high melting and boiling points. | They have low melting and boiling points. |
| 3. | Conductivity | They are bad conductors of electricity in solid state but are good conductors in the molten or aqueous states. | They do not conduct electricity. |
| 4. | Solubility | They are generally soluble in water but insoluble in organic solvents. | They are generally soluble in organic solvents but insoluble in water. |
| 5. | Rate of Reaction | They consist of ions. So, their reactions in solutions are fast. | They consist of molecules. So, their reactions in solutions are slow. |
