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 ...

A NUCLEOPHILIC SUBSTITUTION REACTION
www.people.vcu.edunucleophilic substitution. The nucleophile, or electron rich species, attacks the electrophilic carbon of the alkyl group to give the substituted product. A different nucleophile is generated as a by-product of the reaction. Table E26-1 on the following page gives a number of examples of nucleophilic substitution reactions.

www.pearsonhighered.comundergo a subsequent electrophilic addition reaction with HBr to form more of the substitution product (Section 6.1). Tertiary alcohols undergo substitution reactions with hydrogen halides faster than secondary alcohols do because tertiary carbocations are more stable and, therefore, are formed more rapidly than secondary carbocations.
