electron on hydrogen to spend most of the time around the O, N, or F. This generates a partial positive charge on the hydrogen atom and a partial negative charge on the O, N, or F atom. The partial positive charge on the H atom is attracted to a partial negative charge on the O, N, or F atom in an adjacent molecule.

7: Reactions of Haloalkanes, Alcohols, and Amines ...
people.chem.ucsb.edu7.1 Nucleophilic Substitution Reactions of Haloalkanes Nucleophilic substitution reactions are ionic reactions that break and make chemical bonds by transfers of pairs of electrons. We illustrate this using a general representation of a nucleophilic substitution reaction in which a halogen (X) is replaced by a new group (N).

11: Free Radical Substitution and Addition Reactions
people.chem.ucsb.eduFree radical halogenation reactions of alkanes and cycloalkanes are substitution reactions in which a C-H is converted to a C-X. R3C-H + X2 → R3C-X + H-X While any of the molecular halogens F2, Cl2, Br2, and I2 will halogenate alkanes and cycloalkanes, Br2 or Cl2 are used most often. We will use bromination (X = Br) to illustrate alkane ...
