Consider the following compounds Arrange these compounds in the increasing order of reactivity with nitrating mixture.

Options

  1. Ac < a < b
  2. Bb < a < c
  3. Cc < b < a
  4. Db < c < a

Correct answer

B. b < a < c

Step-by-step solution

Electrophilic aromatic nitration reactivity depends on the electronic effects of substituents. Compound a (chlorobenzene) has a weakly deactivating chlorine group. Compound b (nitrobenzene) has a strongly electron-withdrawing nitro group, making it significantly deactivated. Compound c (anisole) has an electron-donating methoxy group, making it highly activated. In order of increasing reactivity with nitrating mixture: nitrobenzene (b) is least reactive due to strong deactivation, chlorobenzene (a) is moderately re
