Question

Name the structure in which there are two phenyl groups attached to the amino group.

Answer 1

Diphenyl amine:

1. The chemical compound diphenylamine has the formula ${\left({\mathrm{C}}_6{\mathrm{H}}_5\right)}_2\mathrm{NH}$.
2. The chemical is an aniline derivative with an amine linked to two phenyl groups.
3. The chemical is a colorless solid, it oxidized impurity in commercial samples causes it to turn yellow.
4. Diphenylamine is produced via thermal deamination of aniline over oxide catalysts. $\underset{\mathrm{Aniline}}{2{\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{NH}}_2\left(\mathrm{l}\right)}\stackrel{∆}{\to }\underset{\mathrm{Diphenyl}\mathrm{aniline}}{{\left({\mathrm{C}}_6{\mathrm{H}}_5\right)}_2\mathrm{NH}\left(\mathrm{s}\right)}+\underset{\mathrm{Ammonia}}{{\mathrm{NH}}_3\left(\mathrm{g}\right)}$.
5. Many common organic solvents dissolve diphenylamine well, and it is moderately soluble in water.
6. Its antioxidant qualities are the reason for its use. Diphenylamine is widely used as an industrial antioxidant, dye mordant, and reagent, as well as a fungicide and antihelmintic in agriculture.

Therefore, Diphenyl amine has two phenyl groups attached to the amino group.
