Crude oil and separation
Describe hydrocarbons, crude oil mixtures and finite fossil resources used as fuels and petrochemical feedstocks.
Explain fractional distillation using the temperature gradient, boiling ranges and condensation levels.
Recall main crude-oil fractions in order and link each to its uses.
Explain chain-length effects on boiling point, viscosity and ease of ignition.
Hydrocarbon patterns and cracking
Describe alkane homologous-series patterns and use the general formula for acyclic alkanes.
Identify saturated alkanes and unsaturated alkenes and describe useful cracking products.
Explain cracking conditions and demand, balance cracking equations and distinguish cracking from physical distillation.
Combustion and pollution
Write complete combustion equations and explain energy release and carbon dioxide production.
Explain incomplete combustion products, reduced useful energy and carbon monoxide and soot hazards.
Explain sulfur dioxide formation, acid rain and effects on ecosystems and carbonate buildings.
Explain high-temperature nitrogen oxide formation and compare measures for reducing different pollutants.
Fuel choices
Evaluate hydrogen and petrol using storage, infrastructure, safety, energy supply and whole-life emissions.
Distinguish hydrogen combustion from fuel cells and explain possible water and nitrogen oxide emissions.
