Organic Chemistry

• The study of carbon-containing compounds and their properties
• Key Functional Groups:
  • Hydroxyl (-OH): Found in alcohols
  • Carbonyl (>C=O): Found in aldehydes and ketones
  • Carboxyl (-COOH): Found in carboxylic acids
  • Amino (-NH2): Found in amines
• Important Reactions:
  • Substitution reactions involve replacing one atom or group with another
  • Addition reactions involve adding atoms or groups to a molecule
  • Elimination reactions involve removing atoms or groups from a molecule
  • Rearrangement reactions involve the rearrangement of atoms or groups within a molecule
• Key Concepts:
  • Isomerism: Molecules with the same molecular formula but different structures (structural and stereoisomerism)
  • Reaction mechanisms: Explain how reactions occur (nucleophilic and electrophilic attacks)
  • Organic synthesis: Building complex molecules from simpler ones

Inorganic Chemistry

• The study of all compounds that are not organic, including metals, minerals, and organometallics
• Types of Compounds:
  • Metals and alloys: Mixtures of metals with other elements
  • Coordination complexes: Consist of a central metal atom surrounded by ligands

  • Acid-base theories: Explain how acids and bases react (Arrhenius, Bronsted-Lowry, Lewis)
  • Molecular geometry: Predicts the three-dimensional shape of molecules (VSEPR theory)
  • Atomic structure: Explains the arrangement of electrons in atoms (orbitals and quantum numbers)
  • Periodic trends: Explain how properties of elements vary across the periodic table (electronegativity, atomic radius)
• Important Laws:
  • Dalton’s Law of Partial Pressures: The total pressure of a mixture of gases is the sum of the partial pressures of each gas
  • Charles's Law relates the volume of a gas to its temperature (at constant pressure)
