  • Terms and terminologies: acids, bases, electrophiles, nucleophiles, hard and soft acid concept as applied to organic molecules.
  • Thermodynamic and kinetic considerations: Enthalpy and free energy of reactions, order and molecularity, rate of reactions and the rate-determining step.
  • Stereochemical considerations: Asymmetric carbons, compounds with one, two or more stereogenic centers. Enantiomers and diastereomers. Racemic mixtures.
  • Determination of reaction mechanisms. Kinetic isotope effects.
  • Aliphanic Nucleophilic substitution reactions: SN1, SN2, SNi mechanisms. Classification of nucleophiles, effect of solvents and other factors affecting the substitution reactions.
