Question

State differences between the properties of ionic compounds and covalent compounds.

Give five differences between electrovalent and covalent compounds.

Answer 1

Sr. No.	Basis of Distinction	Electrovalent (Ionic) Compounds	Covalent compounds
1.	Physical State	They are generally crystalline solids.	They are generally volatile liquids or gases.
2.	Melting and Boiling Points	They have high melting and boiling points.	They have low melting and boiling points.
3.	Conductivity	They are bad conductors of electricity in solid state but are good conductors in the molten or aqueous states.	They do not conduct electricity.
4.	Solubility	They are generally soluble in water but insoluble in organic solvents.	They are generally soluble in organic solvents but insoluble in water.
5.	Rate of Reaction	They consist of ions. So, their reactions in solutions are fast.	They consist of molecules. So, their reactions in solutions are slow.
