Know how aromatic amines are produced and their use in making dyes. 3.3.11.2 Base properties. Understand the nature of amines and why different amines have different base strengths. 3.3.11.3 Nucleophilic properties. Understand that amines are nucleophiles in their reactions with halogenoalkanes (nucleophilic substitution), acyl chlorides and acid anhydrides, including mechanisms. production of aromatic amines and identify their use in making dyes.
