- What is crude oil? Crude oil is the remains of an ancient biomass. It's a finite resource that's found in rocks
- The definition of crude oil is: An infinite resource that's found in rocks. It's a very large number of compounds. These molecules are hydrocarbons
- Hydrocarbons are only made up of hydrogen and carbon molecules.
- Alkanes are saturated chains that don't have double bonds. The first four alkanes are methane, ethane, propane and butane.
- Alkenes are unsaturated hydrocarbons. There's a double bond between two of the carbons.
- Fractional distillation is the process of separating the mixture of hydrocarbons in crude oil. The oil is evaporated and left to cool and condense. The different fractions have different boiling points, so they will all condense at different temperatures
