Solution

Electrovalent Compounds
Covalent Compounds
The chemical bond that is formed by the transfer of electrons from one atom to another is termed as an ionic bond. It is formed when one of the atoms can lose electrons to attain inert or noble gas electronic configuration and the other atom needs electrons to acquire the noble gas configuration. Compounds in which atoms are connected to each other via ionic bonds are termed as ionic or electrovalent compounds.
The chemical bond that is formed by the sharing of electrons between two atoms is known as a covalent bond. It is formed when both the atoms which are reacting require electrons to attain the nearest noble gas configuration. Compounds in which atoms are connected to each other via covalent bonds are termed as covalent or molecular compounds.
2. For example: Sodium chloride (NaCl) and Potassium chloride (KCl). 2. For example: Methane (CH₄) and Water (H₂O).
3. Ionic compounds consists of ions. 3. Covalent compounds consists of molecules.
4. These compounds have high boiling and melting point. 4. These compounds generally have low boiling and melting point.
5. These compounds are generally water soluble. 5. These compounds are generally water insoluble.
6. These compounds when dissolved in Water generates electricity. 6. These compounds do not generate or produce electricity.
