### Melting Point Comparison**Question:** Which would you expect to have the highest melting point?1. CaO2. MgO**Because:**1. The internuclear distance is smaller, therefore the force is stronger and requires more energy to overcome.2. The charge is higher, therefore interactions are stronger and require more energy to overcome.**Options:**- A) II, II- B) I, I- C) I, II- D) II, I
