प्रश्न
Which would you expect to have a higher melting point, magnesium oxide or magnesium fluoride? Explain your reasoning.
थोडक्यात उत्तर
उत्तर
- Magnesium oxide has very strong ionic bonds as compared to magnesium fluoride.
- Mg2+ and O2- have charges of +2 and -2, respectively.
- Oxygen ion is smaller than fluoride ion.
- The smaller the ionic radii, the smaller the bond length in MgO and the bond is stronger than MgF2.
- Due to more strong bond nature in MgO, it has a high melting point than MgF2.
