H-bonding acts as a bridge between _?
Correct answer: B. Two electronegative atoms and H atoms
- A. Two electronegative atoms
- B. Two electronegative atoms and H atoms
- C. Two H atoms
- D. None of these options are correct
Explanation
Hydrogen bond acts as a bridge between hydrogen atom and two electronegative atoms. For example, consider two water molecules joined by hydrogen bond.H-O-H.....O-H-H.In this dimer, linkage O...H-H is a hydrogen bridge. Note that we are not asked the bonds hydrogen makes in hydrogen bridge. Rather we are asked the purpose of hydrogen bridge and that is to connect two electronegative atoms.

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.
