Distinguish between ionic and covalent c...

Distinguish between ionic and covalent compounds under the following properties:
(a) Strength of forces between constituent elements
(ii) Solubility of compounds in water
(c ) Electrical conduction in substances

Text Solution

Verified by Experts

(a) Ionic compounds have strong force of attraction between the oppositely charged ions (e.g `Na^+ and Cl^(-))`, so they are solids . Covalent compounds have weak force of attractio between their molecules so they are usually liquids or gases.
(b) IOnic compounds are soluble in water but covalent compounds are insoluble in water.
(c ) Ionic compounds conduct electricity when dissolved in water or when melted because they contains they (charged particles) But covalent, compounds like glucose do not conduct electricity because they do not contain ions.
