  • Classification, structure and nomenclature of amines
  • Preparation: reduction of nitro compounds, ammonolysis, Gabriel phthalimide synthesis, Hoffmann bromamide reaction
  • Basic character of amines and comparison in gaseous and aqueous phase
  • Reactions: acylation, carbylamine test, Hinsberg test, reaction with nitrous acid
  • Electrophilic substitution in aniline: bromination, nitration, sulphonation
  • Diazonium salts: preparation, Sandmeyer, Gattermann, coupling reactions

What examiners usually ask

  • Arrange in increasing order of basic strength in aqueous solution: C2H5NH2, (C2H5)2NH, (C2H5)3N, NH3 and explain
  • How will you distinguish between primary, secondary and tertiary amines using Hinsberg's reagent?
  • Convert aniline to chlorobenzene and to p-hydroxyazobenzene via the diazonium salt

Exam tip

Why aniline does not undergo Friedel-Crafts and why it is acetylated before nitration are repeated reasoning questions; also memorise the diazonium conversion chart (Sandmeyer with CuCl/CuBr/CuCN, Gattermann with Cu powder, H3PO2 for benzene, coupling for dyes).
