Which of the following non-polar molecules has the highest boiling point? (Refer Page 15 - 17 of Intermolecular Forces)
CH4; molar mass = 16.04 g/mol
CCl4; molar mass = 153.82 g/mol
PF5; molar mass = 125.966 g/mol
Rn; molar mass = 222.01758 g/mol
H2O and NH3 are polar molecules that can form the strongest type of intermolecular force (hydrogen bonding). However, the boiling point of H2O is 100.00 °C whereas NH3 is -33.34 °C.
Why is that so? (Refer Page 32 of Intermolecular Forces)
H2O can form more hydrogen bonds than NH3
H2O can form less hydrogen bonds than NH3
O on the H2O is more electronegative than N on the NH3
Between HF and H2O... which one has a higher boiling point? (Refer Page 32 of Intermolecular Forces)
H2O
HF

Why do the ice cubes float on liquid water? (Refer Page 39 - 43 of Intermolecular Forces)
Due to the "open structure" of the arrangement of water molecules when cooled.
Due to the "extensive structure" of the arrangement of water molecules when cooled.
Due to the "open structure" of the arrangement of air when water is cooled.
