Identify the class of $\left(\mathrm{C}_6 \mathrm{H}_5\right)_3 \mathrm{~N}$ ?

  • A
    $3^{\circ}$ aliphatic simple amine
  • B
    $3^{\circ}$ aromatic mixed amine
  • Correct answer
    C
    $3^{\circ}$ aromatic simple amine
  • D
    $3^{\circ}$ aliphatic mixed amine

Solution

- The compound $\left(\mathrm{C}_6 \mathrm{H}_3\right)_3 \mathrm{~N}$ is triphenylamine. - It is an aromatic amine because the nitrogen atom is bonded to three phenyl groups $\left(\mathrm{C}_6 \mathrm{H}_5\right)$, which are aromatic rings. - It is a tertiary $\left(3^{\circ}\right)$ amine because the nitrogen is bonded to three carbon atoms, all part of the phenyl groups, with no hydrogen atoms attached directly to the nitrogen.

Hence, the correct answer is option: 'C'.
