Chemistry

Physical Chemistry

• Definition: Branch of chemistry that deals with the physical properties and changes of substances.
• Key Concepts:
  • Thermodynamics: Study of energy changes in chemical reactions.
    • Laws of thermodynamics (e.g., conservation of energy)
    • Enthalpy, entropy, and free energy concepts.
  • Chemical Kinetics: Investigates the rates of chemical reactions.
    • Factors affecting reaction rates: concentration, temperature, catalysts.
    • Rate laws and mechanisms.
  • Quantum Chemistry: Application of quantum mechanics to chemical systems.
    • Wave functions and the Schrödinger equation.
    • Electron configurations and atomic orbitals.
  • Equilibrium: The state where reactants and products are formed at the same rate.
    • Le Chatelier's Principle.
    • Equilibrium constants (Kc, Kp).
  • Statistical Mechanics: Relates macroscopic properties to microscopic behaviors of particles.

Organic Chemistry

• Definition: Study of the structure, properties, composition, reactions, and synthesis of carbon-containing compounds.
• Key Concepts:
  • Hydrocarbons: Compounds consisting only of carbon and hydrogen.
    • Types: Alkanes (single bonds), alkenes (double bonds), alkynes (triple bonds).
  • Functional Groups: Specific groups of atoms that impart characteristic properties.
    • Examples: Alcohols (-OH), carboxylic acids (-COOH), amines (-NH2), et al.
  • Stereochemistry: Study of spatial arrangement of atoms.
    • Isomers: Structural isomers and stereoisomers (geometric and optical).
  • Reaction Mechanisms: Detailed steps of how reactants transform into products.
    • Types: Nucleophilic substitution, electrophilic addition, elimination reactions.
  • Biomolecules: Organic molecules essential for life (proteins, carbohydrates, lipids, nucleic acids).
• Laboratory Techniques:
  • Spectroscopy (NMR, IR, UV-Vis) for structure determination.
  • Chromatography (TLC, HPLC) for separation and purification.
