Question
Arrange the following species in order of decreasing melting points: Ne, KF, C2H6, MgO, and H2S.
Be sure to justify your answers whenever you are asked a question like this. Note that compounds with strong intermolecular bonds hold to one another much more tightly. You can use the type of intermolecular bonding to arrange the melting points based on this, since melting involves breaking bonds. Do not simply list them in order of their melting points, which you could find by looking them up. Instead, explain which type of bonding each displays and why (which will be the bulk of your score on this question). Note also that MgO is an ionic compound, so that the “intermolecular” bonding is really between Mg2+ and O2- ions.
