How do covalent compounds differ from ionic compounds ?


A comparison of the properties of covalent and ionic compounds is presented below:

Covalent compounds:

1. Covalent compounds are formed by the mutual sharing electrons.

2. They have low melting and boiling points.


3. Covalent compounds are soluble in non-polar (organic) solvents such as benzene, carbon tetrachloride, etc., and they are generally insoluble in polar solvents such as water.

4. Except polar compounds, they are nonconductors of electricity, i.e., they are electrical insulators.

5. Covalent compound react slowly due to the molecular nature of the reactions.

Ionic compounds

1. Ionic compounds are formed a complete transfer of elements.


2. They have high melting and boiling points.

3. Ionic compounds are soluble in water and generally insoluble in organic solvents.

4. Ionic compounds are good conductors of electricity in the molten state as well as in aqueous solutions.

5. Ionic compounds react fast due to the ionic nature of the reactions.
