ionic compound tend to have a high melting point because of their high electronegativity.
CaCl2 is ionic, is solid and will have the highest melting point. The rest are covalent compounds.
This is a phase change from solid to liquid which occurs at a fixed temperature when the ionic lattice breaks down. In general ionic compounds are high melting.
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 have a higher melting point.
Ionic compounds generally have higher melting and boiling points.
Ionic compounds have a higher melting point.
Covalent compounds have a lower melting point.
Covalent compounds have a lower melting point.
CaCl2 is ionic, is solid and will have the highest melting point. The rest are covalent compounds.
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.
