Halogenoalkanes and nucleophiles

R-Hal + H2O

  • Heat under reflux
  • Also known as hydrolysis

R-Hal + OH-

  • Heat under reflux

R-Hal + NH3

  • Heat with concentrated ammonia solution in a sealed tube

When making a halogenoalkane, sodium hydrogencarbonate added to remove any acidic impurities and anhydrous sodium sulphate is used as a drying agent.
