Topics in Basic Principles of Organic Chemistry
Structural Representation of Organic Molecules
- Structural formula shows all atoms and bonds in a molecule using dashes
- Electron dot structures (Lewis structures) show valence electrons as dots
- Condensed formula simplifies structural formula by grouping identical atoms
Classification of Organic Compounds
- Classification based on carbon skeleton: acyclic (aliphatic) vs cyclic compounds
- Acyclic compounds have straight or branched carbon chains
- Cyclic compounds contain rings: homocyclic (carbocyclic) or heterocyclic
IUPAC Nomenclature
- IUPAC system provides unique names for organic compounds
- Name consists of: root (carbon chain) + suffix (functional group) + prefix (substituents)
- For alkanes: stem name based on number of carbons (meth-, eth-, prop-, but-, etc.)
Isomerism - Structural Isomerism
- Isomers have same molecular formula but different structures or spatial arrangements
- Structural isomers have different structural formulas
- Chain isomerism: different carbon skeletons (e.g., butane vs 2-methylpropane)
