37. Which of the following compounds would be expected to have the highest melting point?

A. NaCl
B. BaCl₂
C. MgCl₂

38. Which of the following molecules are unstable or do not exist?

A. AlCl₃



Answer :

Final answer:

BaCl2 is expected to have the highest melting point due to its high lattice energy.


Explanation:

Lattice Energy: The compound with the highest lattice energy would have the highest melting point. In this case, BaCl2 would be expected to have the highest melting point since it has the greatest lattice energy due to the presence of multiple chloride ions per formula unit.
