Why does H2O boil at 100 C while H2S boils at -60 C?
AWater has a larger molar mass
BWater has stronger London forces
CWater molecules are nonpolar
DWater has strong hydrogen bonding
Answer & Solution
Correct answer: D. Water has strong hydrogen bonding
Water has the smallest molar mass of the group, so its high boiling point comes from extensive hydrogen bonding.
