Question: This table indicates the freezing and boiling points of several molecules: Molecule Freezing Point (C) Boiling Point (C) Water 0 100 Carbon tetrachloride (CCl4) -

This table indicates the freezing and boiling points of several molecules: Molecule Freezing Point (°C) Boiling Point (°C)
Water 0 100
Carbon tetrachloride (CCl4) - 23 77
Methane (CH4) - 182 - 164
Carbon tetrachloride and methane are non-polar molecules. How does the polarity and non-polarity of these molecules explain why the freezing and boiling points for methane and carbon tetrachloride are so much lower than those for water?
