  1. Nucleophilic substitutions
    1. SN1 reaction of 3°, allylic, and benzylic halides (Section 11.4 and Section 11.5)
      The S N 1 reaction of tertiary halide forms a carbocation intermediate, which further reacts with a nucleophile to yield a halide ion and a substitution product.
    2. SN2 reaction of 1° and simple 2° halides (Section 11.2 and Section 11.3)
      The S N 2 reaction between an alkyl halide and nucleophile forms a halide ion and substitution product with inversion of configuration.
  2. Eliminations
    1. E1 reaction (Section 11.10)
      The E 1 reaction of an alkyl halide forms a carbocation intermediate, which is deprotonated to yield an alkene and H-X.
    2. E1cB reaction (Section 11.10)
      The E 1 C B reaction of an alkyl halide in concentrated base forms a carbanion intermediate through abstraction of hydrogen alpha to carbonyl, which reacts to produce an allylic carbonyl.
    3. E2 reaction (Section 11.8)
      The E 2 reaction mechanism of bromoalkane with a base such as K O H forms an alkene in one step.
