Crude Oil 2

Crude oil contains many hydrocarbons that behave differently. This GCSE Chemistry quiz checks how we classify them, predict properties, and link structure to fuel use.

Fascinating Fact:

Most hydrocarbons in crude oil are alkanes, which are saturated compounds with only single carbon to carbon bonds. Alkanes have the general formula CnH2n+2.

In GCSE Chemistry, crude oil is used to explore hydrocarbon families and how structure links to properties. You look at why crude oil must be refined, how we sort hydrocarbons into groups, and how chain length affects boiling point, viscosity, and ease of ignition.

Key Terms

  • Hydrocarbon: A compound made only from hydrogen and carbon atoms.
  • Homologous series: A family of organic compounds with similar structures, similar reactions, and a pattern in their properties.
  • Saturated: A compound with no carbon-carbon double bonds, so it cannot add more hydrogen atoms without changing the structure.

Frequently Asked Questions (Click to see answers)

How do you classify hydrocarbons in GCSE Chemistry?

In GCSE Chemistry, hydrocarbons are classified into families such as alkanes and alkenes. You use the type of bonding and general patterns in reactions to group them into a homologous series.

What is the difference between an alkane and an alkene?

An alkane is less reactive and does not decolourise bromine water, while an alkene is more reactive and can decolourise bromine water. The difference comes from the presence of a carbon-carbon double bond in alkenes.

Why do longer-chain hydrocarbons have higher boiling points?

Longer-chain hydrocarbons have stronger intermolecular forces because their molecules are larger and have more surface area. More energy is needed to separate the molecules, so their boiling points are higher.
