Question

explain why ionic compounds have high melting point

Answer 1

In ionic compound there is a strong attraction force between atoms which require very large amount of heat to break this force .. Ionic compounds are very strong. A lot of energy is required to break them. Therefore ionic compounds have high melting point.

Answer 2

This is because of the strong attractive electrostatic forces holding the oppositely charged ions together and a large number of ionic bonds in the crystal lattice. These require a lot of thermal energy to overcome and hence have both high melting and boiling points.
