Q24 / 180 · KCET 2020 · Chemistry

Hinsberg's reagent is

  • A
    $\left(\mathrm{CH}_{3} \mathrm{CO}\right)_{2} \mathrm{O} /$ pyridine
  • Correct answer
    B
    $\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{SO}_{2} \mathrm{Cl}$
  • C
    $\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{SO}_{2} \mathrm{NH}_{2}$
  • D
    $\mathrm{CH}_{3} \mathrm{COCl} /$ pyridine

Solution

Hinsberg reagent is $\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{SO}_{2} \mathrm{Cl}$, (benzene sulphonyl chloride) which is used for detection and confirmation of primary, secondary and tertiary amines.

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