Ionic compounds do not have a specific melting point in the way that molecular substances do. Ionic compounds are typically solids at room temperature and have high melting points. The melting point of an ionic compound depends on factors such as the strength of the ionic bonds and the arrangement of ions in the crystal lattice.
Ionic compounds consist of positively charged ions (cations) and negatively charged ions (anions) held together by electrostatic forces. The melting point is the temperature at which the ionic bonds are weakened enough for the solid to transition into a liquid state. Because ionic bonds are strong, ionic compounds generally have high melting points.
Common examples of ionic compounds include table salt (sodium chloride, NaCl) and calcium oxide (CaO). Their melting points are relatively high: sodium chloride melts at 801 degrees Celsius (1474 degrees Fahrenheit), and calcium oxide has a melting point of about 2,572 degrees Celsius (4,662 degrees Fahrenheit).
It's important to note that the melting points of ionic compounds can vary depending on the specific compound and its structure.
CaCl2 is ionic, is solid and will have the highest melting point. The rest are covalent compounds.
Ionic compounds have strong electrostatic forces of attraction between oppositely charged ions, which require more energy to overcome compared to the weaker intermolecular forces in molecular compounds. This results in higher melting points for ionic compounds.
Ionic compounds have higher melting points than covalent compounds. Common table salt, sodium chloride, is an ionic compound and has a melting point of 801 oC. Table sugar, sucrose, a covalent compound, has a melting point of about 186 oC.
Molecular compounds tend to have lower melting points compared to ionic compounds. This is because molecular compounds are held together by weaker intermolecular forces, such as van der Waals forces or hydrogen bonds, whereas ionic compounds are held together by strong electrostatic forces between ions. The higher the melting point, the stronger the bonds in the compound.
Ionic compounds typically have high melting points because the electrostatic forces holding the ions together are strong, requiring a lot of energy to break the bonds. As a result, ionic compounds usually melt at high temperatures, often above 500°C.

If the melting point is at 1240 degrees C then it is most likely an ionic compound, because ionic compounds have their melting points above 800 degrees C while the molecular compounds have their melting point at or below room temperature.
