Question 1

The melting point of xenon tetrafluoride (XeF4\text{XeF}_4XeF4​) is significantly higher than that of sulfur tetrafluoride (SF4\text{SF}_4SF4​).

Explain why the melting points of these two compounds are different.

In your answer you should:

  • Give the shape of each molecule and explain why each has that shape.
  • Explain how the shape of each molecule determines its polarity.
  • Explain how these factors influence the intermolecular forces and the difference in melting points.
