Why does H₂O have a much higher boiling point than H₂S?
A.Water molecules hydrogen bond; H₂S does not
B.H₂S has the larger molar mass
C.Water is more dense than H₂S
D.H₂S is ionic
Explanation
Core Concept
Oxygen's small size and high electronegativity make water's O–H bonds strongly polar, producing a hydrogen-bonded network that takes far more energy to break than H₂S's weak dipole–dipole and dispersion forces.
Correct Answer
AWater molecules hydrogen bond; H₂S does not
