Question

Arrange the three ionic compounds sodium chloride, magnesium chloride, and aluminum chloride in order of increasing melting point. A)NaCl < MgCl₂ < AlCl₃ B)MgCl₂ < NaCl < AlCl₃ C)AlCl₃ < MgCl₂ < NaCl D)AlCl₃ < NaCl < MgCl₂ E)NaCl < AlCl₃ < MgCl₂

Quizplus · Accepted Answer

The melting point of ionic compounds is influenced by the charge and size of the ions. AlCl3 has the highest melting point due to the high charge of Al3+, followed by MgCl2, and then NaCl with the lowest melting point.
