The difference between Electrovalent and Covalent compounds are :
Electrovalent compounds
- Electrovalent compounds are formed by complete transfer of electrons in KCI (K. + .CI: — K+ CI–)
- Electrovalent compounds are made up of ions.
- Electrovalent compounds are heard, crystalline solids e.g. Na CI, Mg CL2
- Electrovalent compounds are usually soluble in water but insoluble in non-polar solvents like CI4
- Electrovalent compounds generally have high melting and boiling points.
- Electrovalent compounds are good conductors of electricity in the molten state and in aqueous solutions but insulators in the solid state.

Covalent Compounds
- Covalent compounds are formed by mutual sharing of electrons as in NH3
- Covalent compounds are made up of molecules.
- Covalent compounds are usually liquids or gases. E.g. CH4, C2 H6, NH3
- Covalent compounds are soluble in non-polar solvents like benzene or carbon tetrachloride and in soluble in polar solvents like water.
- Covalent compounds generally have low melting and boiling points.
- Covalent compounds are bad conductors of electricity.
