Vedclass · Answer

(A) $BF_3$ has a trigonal planar structure,making it non-polar with a dipole moment of $0 \ D$. In $NH_3$,the orbital dipole due to the lone pair and the bond dipoles of $N-H$ bonds are in the same direction,resulting in a large net dipole moment of $1.47 \ D$. In $NF_3$,the orbital dipole due to the lone pair and the bond dipoles of $N-F$ bonds are in opposite directions,resulting in a smaller net dipole moment of $0.24 \ D$. Therefore,the correct order of increasing dipole moments is $BF_3 < NF_3 < NH_3$.
