Study Notes
Organic Compounds
- Organic compounds contain carbon and hydrogen, often with other elements like oxygen, nitrogen, or sulfur.
- They typically have covalent bonds.
- They can form large chains or rings.
Hydrocarbons
- Hydrocarbons are compounds containing only carbon and hydrogen.
- Types include:
- Alkanes: Saturated (only single bonds between carbon atoms).
- Alkenes: Unsaturated (at least one double bond).
- Alkynes: Unsaturated (at least one triple bond).
- A saturated hydrocarbon has all its carbon atoms bonded to the maximum number of hydrogen atoms.
Nomenclature of Organic Compounds
- IUPAC (International Union of Pure and Applied Chemistry) provides systematic naming for organic compounds.
- Names reflect chain length, functional groups, and substituents.
- Example: CH3CH2OH is named ethanol.
Functional Groups
- Functional groups are specific groups of atoms within a molecule that are responsible for characteristic chemical reactions.
- Examples:
- Carboxylic acids: -COOH (carboxyl group)
- Alcohols: -OH (hydroxyl group)
Solubility of Organic Compounds
- Carboxylic acids and alcohols are soluble in water due to hydrogen bonding.
- Solubility decreases as the carbon chain length increases (hydrophobic effect).
Molecular and Structural Formulas
- Molecular formulas show the number and type of atoms within a molecule (e.g., C2H4O2).
- Structural formulas show the arrangement of atoms within a molecule (e.g., CH3COOH).
Bonding and Reactivity
- Alkanes (single bonds): Less reactive, undergo combustion and substitution reactions.
- Alkenes (double bonds): More reactive, undergo additional reactions.
- Alkynes (triple bonds): Highly reactive, undergo additional reactions.
