Q26 / 200 · WBJEE 2013 · Chemistry

When aniline is nitrated with nitrating mixture in ice cold condition, the major product obtained is

  • Correct answer
    A
    $p$ -nitroaniline
  • B
    2,4 dinitroaniline
  • C
    $o$ -nitroaniline
  • D
    $m$ nitroaniline

Solution

Direct nitration of aniline with nitric acid gives a complex mixture of mono, di- and tri-nitro compounds and oxidation products. If $-\mathrm{NH}_{2}$ group is protected by acetylation and then nitrated with nitrating mixture, $p$ -isomer is the main product. Figure

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