In NH3, dominant Van der Waal's force among following is:
Correct answer: D. Hydrogen bonding
- A. London dispersion forces
- B. Dipole induced dipole forces
- C. Dipole-dipole forces
- D. Hydrogen bonding
Explanation
Hydrogen bonding is a specific type of dipole-dipole interaction that occurs when hydrogen is bonded to highly electronegative atoms like oxygen, nitrogen, or fluorine. In the case of NH₃, where hydrogen is bonded to nitrogen, hydrogen bonding is indeed the dominant 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.
