Question

Why electrovalent compound has high melting and boiling point and covalent compound has low melting and boiling point?

Answer 1

Explanation:

electro colvalent bond exert a coulombic force between the oppositly charged ions hence making an ionic bond between the particles covalent compound tend to share elections and an electrostatic force is absent hence we say that ionic or electrovalent compound have high melting point

Answer 2

Answer:

Covalent compounds have low melting and boiling points because they are made up of electrically neutral molecules. So, the force of attraction between the molecules of a covalent compound is very weak.

Explanation:

Only a small amount of heat energy is required to break these weak molecular forces. That is why covalent compound have low melting boiling points.

hope it's help u....
