Study the following graphs for the boiling points of some substances:Which of the above graph shows that some members of the graph have hydrogen bonding?
Correct answer: C. III + IV + V
- A. I + IV
- B. II + IV
- C. III + IV + V
- D. I + II + III
Explanation
Hydrogen bonding is found between the hydrogen atom of one molecule (which is covalently bonded to an electronegative atom) and the fluorine, oxygen and nitrogen of another molecule. It is represented with dotted lines.

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.
