Overview

Organic compounds containing nitrogen include amines, nitro compounds, cyanides, isocyanides, and diazonium salts. Their chemistry is governed by the position of nitrogen in the molecule, the effect of substituents on electron density, and the stability of intermediates such as diazonium ions. Aroma

Key Concepts

Aniline contains the NH2 group attached

Aniline contains the NH2 group attached to a benzene ring. The NH2 group releases electron density into the ring, so aniline undergoes electrophilic s

Aniline is converted to acetanilide by

Aniline is converted to acetanilide by acetylation of the NH2 group. The acetyl group withdraws electron density from nitrogen, reducing activation of

All amines are basic because nitrogen

All amines are basic because nitrogen has a lone pair. Among aliphatic amines, the general order of basic strength is 2° amine > 1° amine > 3° amine.

Aromatic primary amines undergo diazotisation

Aromatic primary amines undergo diazotisation with NaNO2 and HCl at 273-278 K to form diazonium salts. These salts are unstable and are used as freshl

The diazonium group can be replaced

The diazonium group can be replaced by H, OH, Cl, Br, I, F, CN, NO2, and aryl groups under suitable conditions. Important named reactions include Sand

Learning Objectives

  • Understand the structure, classification, and reactions of amines, nitro compounds, cyanides, isocyanides, and diazonium salts
  • Explain why aniline is o- and p-directing and why acetylation is used as a protection step
  • Compare the basic strength, boiling points, and solubility of different classes of amines
  • Describe the preparation, properties, and reactions of nitrobenzene
  • Distinguish between nitroalkanes and alkyl nitrites, and between cyanides and isocyanides
