Aryl halides are extremely less reactive towards nucleophilic substitution. Predict and explain the order of reactivity of the following compounds towards nucleophilic substitution:
This is a short answer type question as classified in NCERT Exemplar
Because of resonance stabilisation, aryl halides are less reactive to nucleophilic substitution. The inclusion of a -NO2, an electron-withdrawing group in the ortho or para position, enhances the aryl halide's sensitivity to substit
