The dipole moment of $NF_3$ is less than that of $NH_3$.

Vedclass · Answer

(B) In $NH_3$,the direction of the dipole moment of the three $N-H$ bonds is in the same direction as the lone pair on the nitrogen atom,resulting in a higher net dipole moment $(1.46 \ D)$.In $NF_3$,the direction of the dipole moment of the three $N-F$ bonds is opposite to the direction of the lone pair on the nitrogen atom,which partially cancels out the net dipole moment,resulting in a lower value $(0.24 \ D)$.Therefore,the dipole moment of $NF_3$ is less than that of $NH_3$.
