Which of the following compounds would be expected to have the highest melting point? A)NCl₃ B)OCl₂ C)MgCl₂ D)LiCl E)CCl₄

Question

Quizplus · Accepted Answer

MgCl2 has the highest melting point because it has the strongest ionic bond due to the high charge and small size of Mg2+ ions, as well as the high electronegativity of Cl- ions, which leads to strong electrostatic attraction between the ions. Ionic bonds generally have higher melting points than covalent bonds or metallic bonds.
