State four differences between electrovalent and covalent compounds.
Electrovalent Compounds | Covalent Compounds |
They are formed from the transfer of electrons from one atom to the other. Ex: NaCl | They are formed from the sharing of electrons between constituent atoms. Ex: CCl4 |
In their molten state, they are good conductors of electricity. | They are generally bad conductors of electricity. |
They have high melting and boiling point due to the strong electrostatic force of attraction. | They have low melting and boiling points. |
They are generally soluble in water and insoluble in organic solvents. | They are generally soluble in organic solvents and insoluble in water. |
