    Study Notes

    Organic Chemistry

    • Study of carbon-based compounds and their properties
    • Carbon atoms can form long chains, branches, and rings due to their ability to form multiple bonds
    • Organic compounds are typically found in living organisms, but can also be synthesized in a laboratory

    Alkanes

    • Saturated hydrocarbons, meaning they have only single bonds between carbon atoms
    • General formula: CnH2n+2
    • Examples: methane (CH4), ethane (C2H6), propane (C3H8)
    • Properties:
      • Low boiling and melting points
      • Insoluble in water, but soluble in non-polar solvents
      • Relatively unreactive, except for combustion reactions

    Hydrocarbons

    • Compounds consisting of only hydrogen and carbon atoms
    • Can be classified into two main categories:
      1. Saturated hydrocarbons (alkanes): single bonds between carbon atoms
      2. Unsaturated hydrocarbons (alkenes and alkynes): one or more multiple bonds between carbon atoms
    • Hydrocarbons are the primary components of fossil fuels, such as petroleum and natural gas
    • Uses:
      • Energy production (fuels, electricity)
      • Manufacturing of plastics, dyes, and other chemicals
      • Lubricants and solvents
