Water has a much higher boiling point than H$_2$S (similar molar mass) because:
AWater has more covalent bonds per molecule than H$_2$S does
BH$_2$S is ionic while water is purely a covalent compound
CWater has stronger van der Waals forces only between molecules
DWater molecules form extensive hydrogen bonds with each other
Answer & Solution
Correct answer: D. Water molecules form extensive hydrogen bonds with each other
Hydrogen bonding among water molecules raises its boiling point well above H$_2$S.
