WebAug 22, 2024 · The usual explanation for the molecular dipole moment of $\ce{NF3}$ being smaller than that of $\ce{NH3}$, despite the $\ce{N-F}$ dipole being stronger than the $\ce{N-H}$ dipole, is that influence of the lone electron pair on nitrogen is to oppose the net $\ce{N-F3}$ dipole, while enhancing that of $\ce{N-H3}$.See, for example, this good … WebThe relatively large difference in the partial charges of each atom in N−H, O−H and F−H bonds allow for very strong dipole-dipole attractions between molecules that contain them) Hydrogen bonds are exceptionally strong because: they involve exceptionally strong dipoles, hydrogen atoms are very small, and fluorine, oxygen, and nitrogen ...
