Web5 apr. 2012 · In earlier work we introduced a simple calculational model for predicting the primary substitution site for nucleophilic substitution involving the replacement of fluorine, initially in aromatic perfluorocarbons [] and subsequently in fluorinated aromatic systems containing both ring heteroatoms (principally nitrogen, but also oxygen, phosphorus and … WebAs only two bonded groups remain, two lone pairs exist. In the outer shell, oxygen with no bonds has 6 electrons, and it would like to have eight. Oxygen with four bonds will have four neighbours' electrons, so it has to shed two of its own six to get to 8. 1 Curtis Wood

WebOne must understand that lone pairs can each be hydrogen bond donors. Solution 2: The answer lies in hydrogen bonding. Hydrogen bond energy depends on the electronegativity of a highly electronegative atom which is bonded to hydrogen. Electronegativity of hydrogen is $2.2$, for oxygen it's $3.44$ and it's $4$ for fluorine.
