Since fluorine is more electronegative than hydrogen, it is expected that the net dipole moment of NF 3 is greater than NH 3. However, the net dipole moment of NH 3 (1.46 D) is greater than that of NF 3 (0.24 D). This can be explained on the basis of the directions of the dipole moments of each individual bond in NF 3 and NH 3. These directions ...

Hydrogen bonding is a special type of dipole-dipole attraction betweenmolecules, not a covalent bond to a hydrogen atom. It results fromthe attractive force between a hydrogen atom covalently bonded toa very electronegative atom such as a N, O, or F atom and another veryelectronegative atom. Hydrogen bond strengths range from 4 kJ to50 kJ per mole of hydrogen bonds.
