ADVERTISEMENTS:

Differentiate between electrovalent (ionic) and covalent compounds

The difference between electrovalent (ionic) and covalent compounds are :

Electrovalent compounds

  1. The are made up of ions
  2. "Chemistry

    They are generally crystalline solids.

  3. They have high m.p. and b.p.
  4. They are easily soluble in water but insoluble in organic solvents, such as benzene, chloroform, etc.
  5. They can be electrolysed.
  6. They are bad conductors of electricity in the solid state, but can conduct electricity in the molten state or in aqueous solution.
  7. The molecules of electrovalent compounds have no definite shape.
  8. In solution, these compounds react very fast.

Covalent compounds

  1. They are made up of molecules.
  2. They are generally gases or liquids under ordinary conditions.
  3. Their m.p. and b.p. are low.
  4. They are insoluble in water but are usually soluble in organic solvents, such as benzene, chloroform, etc.
  5. Generally, they cannot be electrolysed.
  6. Covalent compounds (except polar covalent compounds) do not conduct electricity.
  7. The molecules of covalent compounds have definite geometrical shapes
  8. In solution, the reactions of these compounds are slow.
