Between NH3 and NF3 which has higher dipole moment and why?
The dipole moment of NF3 = 0.24D. As, both the N-H bond are in the same direction it adds to the bond moment of the lone pair, while N-F bond are in the opposite direction, so they partly cut the bond moment of the lone pair. Thus, dipole moment of NH3 is higher than that of NF3.
