Ring Substitution Reaction In Nitroarenes

Ring Substitution Reaction In Nitroarenes

  • Electrophilic substitution
  • The nitro group in nitrobenzene is a deactivating group and deactivates both the ortho and para position in the ring due to conjugation.
  • The meta position becomes comparatively the point of high electron density.
  • Electrophilic substitution reaction occurs in meta-position.

 

  • Nucleophilic substitution reaction

The nitrobenzene is the points of low electron density (positively charged). Nucleophile attacks on intense heating. Some nucleophilic substitution reactions are:
