प्रश्न
Explain the following:
Electrovalent compounds have a high melting point and boiling point while covalent compounds have low melting and boiling points.
टीपा लिहा
उत्तर
Electrovalent compounds have a strong force of attraction between the oppositely charged ions, so a large amount of energy is required to break the strong bonding force between ions. So, they have high boiling and melting points.
Covalent compounds have weak forces of attraction between the binding molecules, thus less energy is required to break the force of binding. So, they have low boiling and melting points.
