Questions and Answers
What is the process by which coal is formed?
What is the process by which coal is formed?
Coal is formed from the accumulation and decay of plant matter over millions of years under heat and pressure, going through stages of peat, lignite, bituminous coal, and anthracite.
What are three common uses of petroleum after it is refined?
What are three common uses of petroleum after it is refined?
Petroleum is used as fuel for vehicles (petrol/gasoline and diesel), as a raw material for producing plastics and rubber, and as a source for making explosives.
Explain the difference between natural gas and petroleum.
Explain the difference between natural gas and petroleum.
Natural gas is a gaseous mixture of low molecular weight hydrocarbons, mostly methane, while petroleum is a liquid mixture of hydrocarbons, primarily alkanes, cyclic alkanes, and aromatics.

Study Notes
Natural Sources of Organic Compounds
- Fossil Fuels: Organic compounds derived from ancient plant and animal matter.
- Coal: Formed from the transformation of plants under heat and pressure (peat → coal). Extraction involves destructive distillation. Yields coal gas, coke, coal tar, and ammoniacal liquor. Used widely as fuel and in organic compound production.
- Petroleum (Crude Oil): A dark, oily liquid found in sedimentary rock. Contains a mixture of hydrocarbons (alkanes, cycloalkanes, aromatics). Used as fuel (petrol, diesel, kerosene) and in the production of many other materials, including rubber, plastics, and explosives.
- Natural Gas: A flammable, gaseous mixture primarily composed of methane, with smaller amounts of ethane, propane, butane, and trace amounts of H₂S, CO₂, and N₂. Refined to remove the impurities. Used as fuel (home, industry, and vehicles) and in fertilizer and carbon black production.
Biological Sources of Organic Compounds
- Plants: A rich source of natural products containing proteins, carbohydrates, vitamins, fats, and oils. Found in various plant parts (leaves, stems, fruits, flowers, seeds, roots).
- Animals: Provide proteins, carbohydrates, vitamins, and fats. Sources include milk, meat, butter, and eggs.
Synthetic Sources of Organic Compounds
- Laboratory & Industrial Preparation: Historically, organic compounds were thought to be produced only by living organisms. The synthesis of urea (H₂NCOH₂) disproved this "Vital Force Theory". Now, countless organic compounds are synthesized commercially in labs and industries.
