Alkanes
Alkanes are saturated hydrocarbons with single carbon-carbon bonds. These pages separate the topic into crude oil, fuels, alternative fuels and alkane reactions so that students can revise the source, use and chemical behaviour of alkanes clearly.
Revision Notes
Work through each part of Edexcel Topic 6 in a structured sequence.
Alkanes from Crude Oil
Revise crude oil as a mixture of hydrocarbons and how fractional distillation separates fractions with different boiling ranges.
Start revisingAlkanes as Fuel
Learn how alkanes release energy during combustion and compare complete and incomplete combustion products.
Start revisingAlternative Fuel
Review alternative fuels and compare their advantages, limitations and environmental implications against fossil fuels.
Start revisingReactions of Alkanes
Revise the key reactions of alkanes, including combustion and free-radical substitution with halogens under ultraviolet light.
