Molecular shape, polarity and intermolecular forces
Main lesson
Polar or nonpolar molecule?
Use this for “Is carbon tetrachloride polar, even though its bonds are?”
The strongest attraction between molecules
Use this for “Which liquid evaporates faster, and which has the higher boiling point?”
Why ice floats
Use this for “Why does ice float on liquid water?”, “How many hydrogen bonds can one water molecule make?” or “Why does water dissolve salt?”
