Which would you expect to have a higher melting point sodium chloride NaCI or aluminum oxide AI203?

The melting point of sodium chloride is 801 0C. The melting point of aluminium oxide is 2 072 0C.


Why is the melting point of sodium chloride is much higher than that of aluminium tetrachloride?

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.


Why does the melting point increase from sodium to aluminium?

The cation becomes more positive from sodium to aluminium, so its attraction for the sea of electrons increases.
