Obviously there is a wide range in bond polarity, with the difference in a C-Cl bond being 0.5 -- considered just barely polar -- to the difference the H-O bonds in water being 1.4 and in H-F the difference is 1.9. This last example is about as polar as a bond can get.
WebMar 6, 2024 · The 29 Si NMR spectrum revealed a doublet of quartets (δ 23.63 ppm and J (29Si–11B) = 66.78 Hz), which underpinned the presence of Si–B and Si–F bonds. Although the spectroscopic data unambiguously affirmed the formation of a compound with a Si(II)–F bond, its structural characterization by X-ray diffraction was still missing.
