NEETChemistryHydrocarbonsMCQ+4 / −1
Among the following compounds the one that is most reactive towards electrophilic nitration is
  1. A
    benzoic acid
  2. B
    nitrobenzene
  3. C
    toluene
  4. D
    benzene
View written solutionFree

Correct answer: C

Due to electron releasing group like —R, —OH etc. increases the electron density at ortho and para position and thus makes the benzene ring more reactive towards electrophile. On the other hand, electron withdrawing groups like — COOH, —NO2 etc. reduces electron density and thus reduces the reactivity of benzene towards electrophile. Thus, the order is
