Hydrocarbons question

2016 · Q110

NEETChemistryHydrocarbonsMCQ+4 / −1
Consider the nitration of benzene using mixed conc.H2SO4 and HNO3. If a large amount of KHSO4 is added to the mixture, the rate of nitration will be
  1. A
    unchanged
  2. B
    doubled
  3. C
    faster
  4. D
    slower
View written solutionFree

Correct answer: D

H2SO4 + HNO3 →\to→ NO2+NO_2^ + NO2+​ + HSO4−HSO_4^ - HSO4−​ + H3O+{H_3}{O^ + }H3​O+

KHSO4 →\to→ K+ + HSO4−HSO_4^ - HSO4−​

Due to common ion effect backward reaction will take place so the formation NO2+NO_2^ + NO2+​ decrease so nitration process will become slower.
