Organic Chemistry Overview

Definition: Study of carbon-containing compounds and their properties.
Key Concepts:
- Functional Groups: Specific groups of atoms that determine the characteristics and reactions of molecules (e.g., hydroxyl, carboxyl, amino).
- Isomerism: Compounds with the same molecular formula but different structures (structural isomers and stereoisomers).
- Reaction Mechanisms: Step-by-step description of how reactions occur, including nucleophiles, electrophiles, and intermediates.
Major Classes of Compounds:
- Alkanes: Saturated hydrocarbons (single bonds).
- Alkenes: Unsaturated hydrocarbons (at least one double bond).
- Alkynes: Unsaturated hydrocarbons (at least one triple bond).
- Aromatic Compounds: Compounds containing benzene rings.
Reactions:
- Addition Reactions: Atoms or groups added to double or triple bonds.
- Elimination Reactions: Removal of atoms or groups to form double or triple bonds.
- Substitution Reactions: Replacement of one atom or group by another.

Definition: Study of inorganic compounds, typically those that do not contain carbon-hydrogen bonds.
Key Concepts:
- Coordination Compounds: Complexes formed by metal ions and ligands (molecules or ions that donate electron pairs).
- Oxidation States: The degree of oxidation of an atom in a compound, indicating the number of electrons lost or gained.
- Crystal Field Theory: Explains the electronic structure and properties of transition metal complexes.
Major Classes of Compounds:
- Salts: Formed from the neutralization of acids and bases.
- Oxides: Compounds of oxygen with another element.
- Acids and Bases: Acids donate protons (H+), while bases accept protons.
Reactions:
- Precipitation Reactions: Formation of a solid from a solution.
- Redox Reactions: Involves transfer of electrons between species.

Definition: Study of the physical properties of chemical systems and the changes they undergo.
Key Concepts:
- Thermodynamics: Study of energy changes (enthalpy, entropy, and Gibbs free energy) in chemical reactions.
- Kinetics: Study of the rates of chemical reactions and the factors affecting them (concentration, temperature, catalysts).
- Quantum Chemistry: Application of quantum mechanics to understand atomic and molecular behavior.
Major Principles:
- Laws of Thermodynamics: Conservation of energy and the directionality of processes.
- Chemical Equilibrium: State where the rates of the forward and reverse reactions are equal.
- Spectroscopy: Techniques used to measure the interaction of light with matter to determine chemical composition.
Applications:
