❤.In NH3, the directionof the orbital dipole moment due to lone pair is in the same direction of the 'resultant dipolemoment' of the 3N-H bonds.
❤.Hence,the net dipole moment of NH3 is positive.
❤. But in NF3, molecule the direction of the orbital dipole moment due to lone pair is in the opposite direction to the 'resultant dipole moment'of the 3 N-F bonds.
❤.Hence, its net dipole moment decreases.
❤. Therefore,dipole moment of NH3 is greater than that of NF3
