Which of the two nh3 and nf3 has higher dipole moment?

Answers

Answered by hridwin

nh3 has more since the difference between electronegativities is more here ,,but in nf3 both are more electronegative,hence less dipole moment.....in nh3 it is away from h,, but in nf3 it is towards f

❤.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
