Melting points are a reflection of the intermolecular forces and intramolecular forces of the compound. The stronger the intermolecular force, the more energy it takes to bring it to a different state.
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.
Covalent compounds have lower melting points compared to ionic compounds because covalent bonds are generally weaker than ionic bonds. In covalent compounds, individual molecules or atoms are held together by shared electrons, which are weaker than the electrostatic attraction in ionic compounds. Hence, less energy is required to break the bonds in covalent compounds, resulting in lower melting points.
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).
Covalent compounds typically have weaker intermolecular forces compared to the strong electrostatic forces present in ionic compounds. This results in covalent compounds having lower melting points as less energy is required to break the intermolecular forces and transition from solid to liquid. Additionally, covalent compounds generally have a more disordered structure, which further contributes to their lower melting points.
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.
Ionic compounds generally have higher melting and boiling points.

All different covalent compounds have different boiling points.
Most covalent compounds have relatively low melting and boiling points, as they are held together by weak intermolecular forces. They are usually insoluble in water but soluble in nonpolar solvents. Covalent compounds tend to be nonconductors of electricity in their solid form.
The differences in melting and boiling points between ionic and covalent compounds are due to the strength of the intermolecular forces present. Ionic compounds have strong electrostatic forces of attraction between oppositely charged ions, resulting in higher melting and boiling points. Covalent compounds have weaker intermolecular forces such as London dispersion forces or dipole-dipole interactions, leading to lower melting and boiling points compared to ionic 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.
Molecular covalent compounds have lower melting points because the inetrmolecular forces are weaker than ionic bonds. Note that giant covalent structures, such as silicon dioxide, can have very high melting points, the key factor is not simply the nature of the bond.
Ionic compounds have melting points higher than covalent compounds.
