Which one of the following hydrogen bonds is stronger than others?
Correct answer: B. Option B
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
Electronegativity trend is F>O>N. The greater the difference between the electronegativity of bonded atoms, the stronger the bond. Fluorine is the most electronegative, hence forming the strongest hydrogen bond.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
