Study Notes
Formula of Organic Compounds
- Molecules of organic compounds can be represented by different types of formulas: Molecular formula, Empirical formula, Structural formula, Condensed formula, and Bond-line formula.
- Molecular formula: Actual number of atoms of each element in a molecule (e.g. Glucose: C6H12O6).
- Empirical formula: Simplest ratio of atoms of each element in a molecule (e.g. Glucose: CH2O).
- Structural formula: Shows all atoms in the molecule and bonds between them (e.g. Propane).
- Condensed formula: Shorthand way of writing molecular formula (e.g. CH3CH2CH3).
- Bond-line formula: Represents structure between carbon-carbon bonds (e.g. CH3CH2CH2CH3).
Classifications of Organic Compounds
- Organic compounds can be classified into two categories: Naturally Occurring Organic Compounds (e.g. Proteins, Fats and Oils, Vitamins) and Synthetic Organic Compounds (e.g. Plastics, Medicines and Drugs, Pesticides).
Properties of Organic Compounds
- Properties of organic compounds differ from inorganic compounds: Bonding with molecules (covalent), Forces between molecules (weak), Normal physical state (gases, liquids or low-melting-point solids), Flammability (often flammable), Solubility in water (insoluble), and Conductivity (non-conductor).
Why is Organic Chemistry Special?
- Catenation is the reason for the presence of the vast number of organic compounds in nature.
- Carbon-carbon bonds are strong, allowing long chains or rings of carbon atoms to form.
- Carbon is unique in forming bonds to itself and with many other elements, including hydrogen and strongly electron-attracting elements.
What is an Organic Compound?
- An organic compound is any member of a large class of gaseous, liquid, or solid chemical compounds whose molecules contain carbon.
- Carbon is a major component of all organic compounds, including carbohydrates, lipids, proteins, and nucleic acids.
