Study Notes
Organic Chemistry
Definition
- Study of carbon-containing compounds and their properties
- Involves the study of structure, properties, and reactions of organic compounds
Characteristics of Organic Compounds
- Typically contain carbon and hydrogen atoms
- May also contain oxygen, nitrogen, sulfur, phosphorus, and halogens
- Often have complex structures and diverse properties
Functional Groups
- Specific groups of atoms within a molecule that determine its chemical properties
- Examples:
- Hydroxyl (-OH)
- Carboxyl (-COOH)
- Amino (-NH2)
- Methyl (-CH3)
Types of Organic Compounds
- Alkanes: saturated hydrocarbons (e.g., methane, CH4)
- Alkenes: unsaturated hydrocarbons (e.g., ethene, C2H4)
- Alkynes: unsaturated hydrocarbons with triple bonds (e.g., ethyne, C2H2)
- Arenes: aromatic hydrocarbons (e.g., benzene, C6H6)
- Carbohydrates: sugars, starches, and cellulose
- Lipids: fats, oils, and waxes
- Amino Acids: building blocks of proteins
- Polymers: large molecules composed of repeating units
Reactions in Organic Chemistry
- Substitution reactions: replacement of one atom or group with another
- Elimination reactions: removal of a leaving group to form a double bond
- Addition reactions: addition of a molecule to a multiple bond
- Oxidation-reduction reactions: gain or loss of electrons
Important Concepts
- Stereochemistry: study of the three-dimensional arrangement of atoms in molecules
- Isomerism: existence of multiple compounds with the same molecular formula but different structures
- Resonance: delocalization of electrons within a molecule
