Question

Distinguish between ionic and covalent compounds under the following properties:- (1) strength of forces between constituens element (2) solubility of compounds in water (3) electrical conduction in substance

Answer 1

1)ionic compound has a very strong inter-ionic forces whereas covalent compounds have comparitively weaker attractive forces between the constituent elements.

2)ionic compounds are soluble in polar solvents such as water but insoluble in polar solvents such as petrol, kerosene etc. whereas covalent compounds are soluble in petrol and kerosene and insoluble in water.

3)ionic compounds conduct electricity in molten form but covalent compounds do not conduct electricity as they do not dissociate into water

Answer 2

ionic bonds are stronger because of their inter ionic force of attraction

ionic bonds are soluble in water whereas covalent bonds are not

ionic bonds conduct electricity whereas covalent  dont
