  • Reactions of Halogeno-alkanes
    • Nucleophilic Substitution
      • Hydroxide OH-
        • warm aqueous Na/K OH
        • Nu is electron donor
      • Cyanide CN-
        • heat under reflux - prevent loss of volatile substances
        • in solution of ethanol (+water?)
        • nitrile + Hal-
      • Ammonia NH3
        • amine + ammonium halide
          • amine formed also Nu so further sub possible
        • heat sealed copper tube
        • N+ (intermediate?)
    • Elimination
      • hot ethanolic conc. NaOH
      • OH- (reagent) is base
  • + NH4Cl
  • isomeric products poss
