Which one of the following H-bond is strong?
Correct answer: C. F-H
- A. O-H
- B. N-H
- C. F-H
- D. Cl-H
Explanation
Hydrogen bonding occurs when a hydrogen atom is bonded to a highly electronegative atom (such as oxygen, nitrogen, fluorine, or chlorine) and forms a weak bond with another electronegative atom in a different molecule or within the same molecule.In the case of the options provided, fluorine (F) is the most electronegative element among oxygen (O), nitrogen (N), fluorine (F), and chlorine (Cl). Therefore, the F-H bond will have the strongest hydrogen bond compared to the other options.

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.
