Adhesive nature of honey and glue is due to the presence of?
Correct answer: A. H-bonding
- A. H-bonding
- B. Dipole dipole forces
- C. Ionic forces
- D. Debye force

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.
