WebApr 12, 2012 · 2,802. Apr 11, 2012. #3. For hydrogen bonding to occur you need at least one species involved to have an H bonded to either an F, O, or N, because these highly electronegative atoms make the F/O/N-H bond very polar, giving H enough partial positive charge to exhibit the strong electrostatic interactions we call hydrogen bonds. WebAlcohols boil cosiderably higher than comparably sized ethers (first two entries), and isomeric 1º, 2º & 3º-amines, respectively, show decreasing boiling points, with the two hydrogen bonding isomers being substantially higher boiling than the 3º-amine (entries 5 to 7). Also, O–H---O hydrogen bonds are clearly stronger than N–H---N hydrogen bonds, …
