Presentation transcript:

Fractional distillation of crude oil Baseline (Flightpath D): Name the different fractions from crude oil. State a use for each fraction from crude oil. Further (Flightpath ): Describe how the trend in colour, viscosity, flammability, and boiling point changes as the length of the hydrocarbon chain changes. Describe how the properties of a fraction of crude oil make it appropriate for its use. Challenge Flightpath): Explain in detail how fractional distillation is used to separate crude oil into fractions. Explain how chain length affects the properties of crude oil fractions. Make predictions about the properties of crude oil fractions from the fraction’s hydrocarbon chain length.

Ask students to state the trend in this data. Plot a bar chart methane (Mr = 16, boiling point = −162 °C) ethane (Mr = 30, boiling point = −89 °C), propane (Mr = 44, boiling point −42 °C), and butane (Mr = 58, boiling point −1 °C). Ask students to state the trend in this data.
