Question

Give reason- covalent compound have low melting point as compared to ionic compound

Answer 1

Answer:

Explanation:

Covalent compounds have weak forces of attraction between the binding molecules. Thus less energy is required to break the force of bonding. Therefore covalent compounds have low melting and boiling point.

Whereas Ionic compounds have high melting points because there is a strong electrostatic force of attraction between the oppositely charged ions and hence a large amount of energy is required to break the strong bonding force between ions.

Answer 2

• The melting and boiling points of molecular compounds are generally quite low compared to those of ionic compounds. ... Ionic solids typically melt at high temperatures and boil at even higher temperatures. For example, sodium chloride melts at 801 °C and boils at 1413 °C.
