Between and which one will have a higher melting point.

Answer»

ting point is DIRECTLY depends upon the intermolecular bonds that are present in the COMPOUND.  The melting point of is 1290℃ and is 178℃.  i) Aluminium fluoride is ionic in CHARACTER, due to its low polarisability of the fluoride ion, so it has a high melting point.  ii) Aluminium chloride is COVALENT in nature due to the high polarising power of aluminium, so it has a low melting point.  III) Aluminium chloride does not have a melting whereas it sublimes.
