The boiling point of ammonia (NH₃) is greater than that of phosphine (PH₃) due to the:
- Dispersion forces
- Dipole-dipole forces
- Hydrogen bonding
- Greater molar mass
Explanation
Ammonia (NH₃) has a higher boiling point than phosphine (PH₃)
Ammonia exhibits hydrogen bonding, a stronger intermolecular force than the dipole-dipole forces in phosphine.
