SUMMARY

The discussion centers on the directing effects of substituents in electrophilic aromatic substitution reactions, specifically comparing the CH3 (methyl) group and the COOH (carboxylic acid) group. CH3 is an electron-donating group that directs incoming radicals to the ortho and para positions due to resonance stabilization. In contrast, COOH is an electron-withdrawing group that directs incoming radicals to the meta position, as it destabilizes the resonance forms at the ortho and para positions.

PREREQUISITES
  • Understanding of electrophilic aromatic substitution mechanisms
  • Knowledge of electron-donating and electron-withdrawing groups
  • Familiarity with resonance structures in organic chemistry
  • Basic concepts of radical stability and reactivity
NEXT STEPS
  • Study the effects of different substituents on aromatic ring reactivity
  • Learn about resonance and its impact on radical stability
  • Explore the mechanisms of electrophilic aromatic substitution in detail
  • Investigate the role of sterics in directing effects of substituents
USEFUL FOR

Chemistry students, organic chemists, and researchers interested in reaction mechanisms and substituent effects in aromatic compounds.

Why does CH3 direct the new coming radical to Para and ortho while COOH directs it to meta?

You have to look at if its an electron withdrawing or electron donor group. What is CH3 and COOH?
