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.
It is not possible for the polar covalent compound to have a lower melting point than the non-polar covalent compound because they have ionic bonds.
The melting point of a compound cannot determine the bonding structure. As an example, both diamond and sodium chloride have higher melting points than 800 centigrade but are covalent and ionic compounds respectively.
Generally the ionic molecules has a higher melting point.
Compared to ionic compounds, covalent compounds have relatively low melting and boiling points because covalent bonds are not as strong as ionic bonds, and it is the bonds which hold materials together in the solid, or more solid phases.

Zinc sulfide is a covalent compound.

Ionic compounds have melting points higher than covalent compounds.
Sodium chloride is an ionic compound whereas AlCl3 is a covalent compound. Ionic compounds have greater melting point due to stronger electrostatic force of attraction.
Compared to ionic compounds, covalent compounds have relatively low melting and boiling points because covalent bonds are not as strong as ionic bonds, and it is the bonds which hold materials together in the solid, or more solid phases.
Covalent compounds have a lower melting point.
Molecular Solids have a lower melting point
ionic compound tend to have a high melting point because of their high electronegativity.
Covalent compounds have a lower melting point.
