Which property is characteristic of ionic but not of covalent compounds? 1. low boiling point 2. non-conductor of electricity in molten state 3. easily vaporizes 4. soft, non-crystalline structure 5. high melting point?

Ionic and covalent bonds are both strong intermolecular forces. They are generally both crystalline in structure. But relatively speaking, ionic bonds are much stronger. As a consequence, they have inherent properties of higher boiling points, higher melting points, lower volatility, etc. Also, ionic bonds display conductive properties because they are strong electrolytes. Thus, the answer is 5) higher melting points.

High melting point is the property of ionic compounds not covalent compounds.

High melting point is the characteristic of ionic but not covalent compounds because they are made up of very strong intermolecular forces which needs high amount of energy in order to change from solid state to liquid state.

High melting point is needed to break the bonds between the molecules of ionic compound as compared to covalent compound so we can say that high melting point is the property of ionic compounds not covalent compounds.
