The correct order of reactivity of the following compounds, towards electrophilic substitution reactions is

Options

  1. AA > B > C > D
  2. BD > C > B > A
  3. CC > B > A > D
  4. DB > C > A > D

Correct answer

C. C > B > A > D

Step-by-step solution

Benzene become less reactive in electrophilic substitution reaction when deactivating group is present in it. aligned & (I= inductive effect & H= hyperconjugation effect & M= mesomeric effect ) aligned Electrophilic substitution reaction is +M,+I,+H effect and 1 -M,-I,-H Hence, correct order is
