Which of the following has higher boiling point?
Correct answer: B. H2O
- A. NH3
- B. H2O
- C. HF
- D. CH4
Explanation
Water has a higher boiling point because the molecule is held together by strong hydrogen bonding which is between the partial positive charge on hydrogen and partial negative charge on oxygen therefore more heat is required to break its bond thus a higher boiling point.

About Hydrogen Bonding
Hydrogen bonding is the strong attraction between hydrogen attached to nitrogen, oxygen or fluorine and an electronegative atom in the same or another molecule. It explains unusual boiling points, viscosity, surface tension, water's properties and the difference between intermolecular and intramolecular hydrogen bonding.
