Vedclass · Answer

(D) $BF_3$ has a trigonal planar geometry and is symmetric,so its net dipole moment is $\mu = 0$.$NH_3$ and $NF_3$ both have a trigonal pyramidal geometry with one lone pair on the nitrogen atom.In $NH_3$,the dipole moments of the $N-H$ bonds and the lone pair are in the same direction,reinforcing each other,resulting in a high dipole moment $(\mu \approx 1.46 \ D)$.In $NF_3$,the dipole moments of the $N-F$ bonds are in the opposite direction to the lone pair's dipole moment,partially canceling each other out,resulting in a lower dipole moment $(\mu \approx 0.24 \ D)$.Therefore,the correct order of dipole moment is $NH_3 > NF_3 > BF_3$.
