Question

What are tarry oxidation products?

Answer 1

Tarry oxidation products:

• The products that are formed when nitric acid oxidizes with aniline are called tarry oxidation products.
• These products are known as side products that may be formed when aniline is not protected during nitration.
• Aniline is a primary aromatic compound with the functional group $-{\mathrm{NH}}_2$ and it is an ortho and para directing group.
• In addition to the nitro derivatives, direct nitration of aniline yields tarry oxidation products.
