$NH_3$

Vedclass · Answer

(A) Both $NH_3$ and $NF_3$ molecules have a pyramidal shape with a lone pair of electrons on the nitrogen atom.In $NH_3$,the orbital dipole due to the lone pair is in the same direction as the resultant dipole moment of the $N-H$ bonds,leading to a higher dipole moment $(\mu = 1.46 \ D)$.In $NF_3$,the orbital dipole due to the lone pair is in the direction opposite to the resultant dipole moment of the three $N-F$ bonds,which decreases the overall dipole moment $(\mu = 0.24 \ D)$.Therefore,the dipole moment of $NF_3$ is smaller than that of $NH_3$.

The dipole moment of $NF_3$ is smaller than
