Which of the following is not considered as an intermolecular force between molecules ?
Correct answer: A. Coordinate covalent bonds
- A. Coordinate covalent bonds
- B. Hydrogen bonds
- C. Debye forces
- D. London dispersion forces
Explanation
Coordinate covalent bonds are intramolecular bonds formed when one atom supplies both electrons in a shared pair, so they are not intermolecular forces. Hydrogen bonds, Debye forces and London dispersion forces act between molecules. The likely mistake is choosing b because hydrogen bonds are strong, but they are still intermolecular forces.

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.
