The melting point of sodium chloride is 801 0C.
The melting point of phosphorus trichloride is -93,6 0C.
Sodium Chloride has a higher melting point because at room temperature it is a solid but Ethyl alcohol has already melted, as it is liquid.
aluminum oxide : Al2O3
The melting point of sodium chloride is 801 0C. The melting point of aluminium oxide is 2 072 0C.

Although they are both molecular structures, sulfur exists as S8 while phosphorus exists as P4. Sulfur has more electrons, therefore also has more Van Der Waals forces, than phosphorus. This means that it will require more heat energy to overcome these forces, causing it have a higher melting point.
Common table salt (sodium chloride) has a much higher melting point than either sodium or chlorine.
The ionic bonding in sodium chloride is much stronger than the internal bonding in either element that forms sodium chloride; therefore, the melting point of the salt is much higher than that of either element that forms the salt.
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.
Sulfur is a larger molecule. It hence experiences greater Van der Waal's force.
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.
CaO - the attraction between a 2+ and a 2- ion is much stronger than between a + and a -.
CaO has a higher melting point.
