H-Bonding acts as a bridge between _.
Correct answer: B. H atom and two electronegative atoms
- A. Two electronegative atoms
- B. H atom and two electronegative atoms
- C. Two H atoms
- D. None of these
Explanation
Hydrogen bonding occurs between the highly electronegative atom of one molecule (oxygen, fluorine, and nitrogen) and the hydrogen atom (directly bonded to oxygen, fluorine, or nitrogen) of a neighboring molecule. In this way, the hydrogen bond itself acts as a bridge between two electronegative atoms of neighboring molecules.

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.
