In which manner is an H-Bond formed in an HF molecule?
Correct answer: B. Zig zag
- A. Random
- B. Zig zag
- C. Tetrahedral
- D. Linear
Explanation
A hydrogen bond forms when the free-electron pair of one HF molecule interacts with the bonded hydrogen of another HF molecule. Due to this approximately 109º bond angle is formed between these orbitals, and the atoms arrange themselves in a zig zag pattern.

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.
