Bond length is minimum in:
Correct answer: D. HF
- A. HCl
- B. H2O
- C. NH3
- D. HF
Explanation
HF consists of a hydrogen atom bonded to a fluorine atom. It is also a polar covalent molecule. The bond between hydrogen and fluorine is stronger and shorter compared to the other options because fluorine is the most electronegative element among them. The strong attraction between hydrogen and fluorine leads to a shorter bond length in HF.

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.
