Organic Chemistry

• Focuses on carbon-containing compounds, their properties, reactions, and structures.
• Functional groups determine the reactivity of compounds, including alcohols, carboxylic acids, and amines.
• Main types of reactions include:
  • Addition: two or more reactants combine
  • Elimination: removal of a small molecule resulting in a double bond
  • Substitution: one functional group is replaced with another
  • Rearrangement: reorganization of the molecular structure
• Isomerism involves:
  • Structural isomers: compounds with different arrangements of atoms.
  • Stereoisomers: same atomic connections but differ in spatial arrangement.
• Key concepts include:
  • Chirality: property of a molecule being non-superimposable on its mirror image, leading to enantiomers.
  • Mechanisms of reactions, such as nucleophilic substitution and electrophilic addition.

Physical Chemistry

• Examines the physical properties and behavior of molecules and the forces acting upon them.
• Thermodynamics involves:
  • Laws of thermodynamics, emphasizing energy conservation and the concept of entropy.
  • Gibbs free energy helps determine the spontaneity of reactions under constant temperature and pressure.
• Kinetics studies the speed of chemical reactions, influenced by:
  • Concentration of reactants, temperature conditions, and the presence of catalysts.
• Quantum chemistry investigates:
  • Wave functions and the foundational Schrödinger equation.
  • Nature of atomic and molecular orbitals.
• Chemical equilibrium is characterized by:
  • The dynamic balance of reactants and products.
  • Le Chatelier's principle, which explains how systems respond to changes in conditions.

Inorganic Chemistry

• Focuses on inorganic compounds, generally excluding those with carbon-hydrogen bonds.
• Coordination compounds involve:
  • Ligands, which are ions or molecules that coordinate to metal atoms.
  • Coordination number and geometry describe how many ligands are attached and the spatial arrangement around the metal.
• Periodic table trends include:
  • Atomic radius: size of atoms increases down groups and decreases across periods.
  • Ionization energy: energy required to remove an electron, increases across periods and decreases down groups.
  • Electronegativity: tendency of an atom to attract electrons; varies similarly to ionization energy.
• Main group elements are grouped based on shared properties, influencing their behavior as acids or bases.
• Organometallic chemistry studies compounds that contain metal-carbon bonds, with significant applications in catalysis.

Analytical Chemistry

• Concentrates on the methods for qualitative and quantitative analysis of substances.
