Study Notes
Organic Chemistry
Definition
- Study of carbon-containing compounds and their properties
- Excludes carbonates, cyanides, and cyanates
Characteristics
- Carbon atoms bonded to other carbon atoms, hydrogen, oxygen, nitrogen, and other elements
- Typically, covalent bonds between atoms
- Can be found naturally or synthesized artificially
Functional Groups
- Specific groups of atoms within a molecule that determine its chemical properties
- Examples:
- Hydroxyl (-OH)
- Carboxyl (-COOH)
- Amino (-NH2)
- Carbonyl (>C=O)
Hydrocarbons
- Compounds consisting of hydrogen and carbon atoms only
- Saturated (single bonds) or unsaturated (double or triple bonds)
- Examples:
- Alkanes (saturated): methane, ethane, propane
- Alkenes (unsaturated): ethene, propene
- Alkynes (unsaturated): ethyne, propyne
Isomerism
- Molecules with the same molecular formula but different structures
- Types:
- Structural isomerism: different bond connections
- Stereoisomerism: same bond connections, different spatial arrangements
- Enantiomerism: non-superimposable mirror images
Reactions
- Types:
- Substitution: replacement of a functional group
- Elimination: removal of a functional group
- Addition: formation of a new bond
- Mechanisms:
- Electrophilic addition
- Nucleophilic substitution
Biomolecules
- Organic compounds found in living organisms
- Examples:
- Carbohydrates: sugars, starches, cellulose
- Proteins: peptides, amino acids
- Lipids: fats, oils, cholesterol
