However, when carrying a single fluorine atom (green sphere) four carbon atoms away from an amine nitrogen center (large blue sphere), a fluoroalkyl group may become labile under very mild assay conditions, such as for the determination of lipophilicity. Such δ‐fluoroalkyl amines suffer ...
(27). By excluding terms corresponding to a \(\pi\)-bond-geminal interacting with lone-pair geminals localized on the fluorine atom \(\hbox {F}_1\), closer to the ethylene molecule, one can check how much the \(\pi\)-bond–lone pairs (LP) interaction contributes to the total ...

The substitution reaction of an alkane with a halogen, including chlorine, fluorine, or bromine, produces halogenated hydrocarbons, also called alkyl halides. Alkyl halides can continue to be modified to form multi-substituted compounds. Common examples include chlorofluorocarbons (CFCs), which were form...
In an SN1 substitution reaction, the halide takes control of the electron pair for a brief moment. The now highly positively charged central carbon atom tries to separate its bonds as much as possible, forming a planar triangular shape instead of a tetrahedron. The second nucleophile may approac...
