Practice

• Compare reaction profiles and activation barriers of H2+H obtained by different methods [H2+H]
• Woodward-Hoffmann rules
  • Get reaction profile for Diels-Alder reaction of butadiene with ethylene [C2H4+C4H6]
  • Get reaction profile for 2+2 cycloaddition reaction of two ethylene molecules
  • Explain the geometry of 2+2 cycloaddition transition state
  • Estimate the ratio of rate constants of C2H4+C4H6 and C2H4+C2H4 reactions
  • Explain the difference between the above two rections using molecular orbital theory and discuss Woodward-Hoffmann rules
• Acid dissociation constant [pKa]
  • Calculate pKa for aniline ortho-substituted by NO2 using aniline as the reference system, see here
  • Check different hydrogen sites for aniline ortho-substituted by NO2
