Exam points

  • use aqueous hydroxide to hydrolyse a halogenoalkane to an alcohol and ethanolic cyanide to form a nitrile
  • use excess ethanolic ammonia under pressure to form an amine and identify the ammonium-halide coproduct
  • use warm aqueous silver nitrate in ethanol to identify halide ions from precipitate colour and solubility
  • describe nucleophilic substitution with correct attacking species, leaving group, charges and curly arrows
