Advertisements
उत्तर
Ionic compounds:
- They are made up of ions and are generally crystalline solids with high melting and boiling points.
- They are soluble in water
- They are good conductors of electricity in aqueous solution and molten state.
- They are not true molecules, but rather a collection of positive and negative ions.
Covalent compounds:
- They are made up of molecules and can exist as soft solids or liquids or gases with low melting and boiling points.
- They are generally insoluble in water
- They are poor conductors of electricity.
- They are true molecules.
