They maintain their bonding far longer than nonpolar molecules can with the addition of heat energy. Remember their slightly negative ends will bind with the slightly positive ends of the adjacent molecule.
Covalent bonds do not melt. Compounds with covalent bonds melt and the melting point depends primarily on whether there are discrete molecules held together by intermolecular forces (which have lower melting points) or giant covalent networks such as in silica or diamond (which tend to have higher melting points).
Ionic compounds have higher melting points because the bond olding the ionic crystal together is stronger than the intermolecular forces (van der Waals) holding covalent molecules together. Giant covalent molecules such as dialmond and silicon dioxide have very high melting points because the lattice is held together by stong covalent bonds
Melting points of covalent compounds are generally lower than those of ionic compounds. This is because covalent compounds have weaker intermolecular forces compared to the strong electrostatic forces present in ionic compounds, so they require less energy to break apart the molecules.
CaCl2 is ionic, is solid and will have the highest melting point. The rest are covalent 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.

Solid molecular covalent compounds consist of molecules held together with intermolecular forces, such as dipole dipole interactions and london dispersion forces.Covalent compounds which are giant molecules such as found in diamond or silica are in fact high melting as the strong covalent bonds have to be broken to break down the crystal.Ionic compounds are generally high melting as the strong ionic bonds have to be broken to break down the crystal lattice.
Ionic compounds have melting points higher than covalent compounds.
Iconic compounds are formed by the transfer of electrons from one atom to another, resulting in the formation of ions held together by electrostatic forces. Covalent compounds are formed by the sharing of electrons between atoms, resulting in the formation of molecules held together by strong covalent bonds. Iconic compounds tend to have higher melting and boiling points compared to covalent compounds.
Ionic Compounds are formed by complete transfer of electrons while Covalent compounds are formed by sharing of electrons. Ionic compounds have higher melting points while covalent compounds have lower.
Ionic compounds generally have higher melting and boiling points.
Diamond is a covalent network solid, and those types of compounds have higher melting points than other types of compound.
