Study Notes

Organic Chemistry

Definition: Study of the structure, properties, composition, reactions, and synthesis of carbon-containing compounds.
Key Concepts:
- Functional Groups: Groups of atoms that determine the characteristics of organic compounds (e.g., alcohols, carboxylic acids, amines).
- Isomerism: Compounds with the same molecular formula but different structures (e.g., structural isomers, stereoisomers).
- Reaction Mechanisms: Pathways through which reactants become products (e.g., nucleophilic substitution, elimination reactions).
- Synthesis: Strategies to create complex organic molecules from simpler ones (e.g., retrosynthetic analysis).

Inorganic Chemistry

Definition: Study of inorganic compounds, typically those not covered by organic chemistry, including metals, minerals, and coordination compounds.
Key Concepts:
- Coordination Compounds: Complexes formed from a central metal atom bonded to surrounding ligands.
- Crystal Field Theory: Explains the electronic structure of transition metal complexes and their colors.
- Acids and Bases: Lewis, Brønsted-Lowry definitions; includes behavior in solutions.

Organic Chemistry

Focuses on carbon-containing compounds, analyzing their structure, properties, and reactions.
Functional Groups: Determine chemical behavior; examples include alcohols (hydroxyl group) and carboxylic acids (carboxyl group).
Isomerism: Involves compounds sharing the same molecular formula but differing in structure; includes structural isomers (different connectivity) and stereoisomers (different spatial arrangements).
Reaction Mechanisms: Details pathways where reactants transform into products, with types like nucleophilic substitution (reaction involving a nucleophile) and elimination reactions (removal of atoms to form double bonds).
Synthesis: Methods for constructing complex organic molecules from simpler entities, utilizing approaches such as retrosynthetic analysis (working backwards from target molecule to available materials).
