1.2.5 Reactions of Alkanes, Alkenes & Alkynes

Substitution of Alkanes

Ex 1: Chloromethane + Hydrogen Chloride

Addition of Alkenes / Alkynes

  • Hydrogenation: Hydrogen atoms added to either side of a double/triple bond

  • Halogenation: Halogen (bromine, chlorine) added to double/triple bond

    • Alkyne → Halogenated Alkene → Alkyl Halide

  • Hydration: Water reacts with alkene/alkyne, producing an alcohol (contains –OH group)

    • Markovnikov’s Rule: the rich get richer.
