SUMMARY

The discussion centers on the electrophilic substitution reactions of amines in aromatic compounds, specifically the influence of substituents on determining the ortho or para positions. Hydroxyl (OH) and amino (NH2) groups are identified as ortho and para directors, while nitro (NO2) groups act as meta directors. This distinction is crucial for predicting the outcome of electrophilic attacks in aromatic chemistry. The reference to the Wikipedia page on arene substitution patterns provides additional context for understanding these mechanisms.

PREREQUISITES
  • Understanding of electrophilic aromatic substitution mechanisms
  • Familiarity with the effects of substituents on aromatic compounds

attack of electrophile at para or ortho position of amine?S.ince para location is substituted with substituent so the ortho position of benzene H atom will be substituted ... My question is which one OH or NO2 determine the para or ortho position?? Why is it so?
 
Physics news on Phys.org
OH and NH2 is ortho and para director, NO2 is meta director for electrophile substitution.
