Question

distinguish between ionic and covalent compounds under the following properties:

(i)strength of forces between constituents elements.

(ii)solubility of compounds in water.

(iii)electrical conduction in substances.

Answer 1

Ionic compounds have very strong inter-ionic forces whereas covalent compounds have comparatively weaker attractive forces between the constituent elements.

Ionic compounds are soluble in water and not in organic solvents whereas covalent compounds are not soluble in water but in organic solvents.

Ionic compounds conduct electricity as they dissociate into ions whereas the covalent compounds do not conduct electricity as they do not dissociate into ions.
