Which will not go for diazotization ?

  • A
    $\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{NH}_{2}$
  • Correct answer
    B
    $\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{CH}_{2} \mathrm{NH}_{2}$
  • C
    Figure
  • D
    Figure

Solution

Diazotisation reactions are shown by primary aromatic amine only as the arene diazonium salt formed is stable at 273-278 K. Compound $\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{CH}_{2} \mathrm{NH}_{2}$ is not an aromatic amine, hence will not give the test/reaction.

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